How to read these answers
Slowness in a game is rarely a single fault. It is usually a limit somewhere: a chip that is doing
all it can, a laptop that has grown too warm to keep going at full speed, or a setting asking for work
the machine was never going to manage at that rate. The questions below separate those cases so you
change the thing that is actually in the way.
Every step is free, and the order is deliberate. Settings first, because they are reversible and
cost nothing; heat and power next, because they explain the slowdowns that arrive after ten minutes;
hardware last, once the earlier steps have shown which part is the limit.
Why does the game stutter when my frame rate looks high?
Short answerBecause the average frame rate hides uneven gaps between frames. A game averaging 90 fps that occasionally takes 40 milliseconds to draw one frame feels worse than a steady 60.
What usually causes it
The counter in the corner reports an average over the last second. Within that second, one
long frame is enough to be felt as a hitch. Those long frames come from work that does not happen
every frame: loading new textures as you move into an area, compiling shaders the first time an effect
appears, or another program briefly taking the processor.
A mismatch between how often the game produces frames and how often the screen refreshes causes a
steadier version of the same thing. Frames arriving slightly out of step with the display are shown
twice or skipped, which reads as judder even while the counter sits at a comfortable number.
What to try first, at no cost
- Play for a few minutes in the same area and see whether the stutter fades. Shader compilation settles after the first encounter with an effect.
- Turn on the game's frame rate limit and set it slightly below your screen's refresh rate.
- Try the vertical sync setting both on and off, and keep whichever is smoother on your screen.
- Close background programs that record, stream or overlay, then test again.
- Switch the game to full screen rather than borderless window, if the option exists.
- If the game stores settings for texture streaming or texture pool size, lower that before lowering anything visual.
When to ask for official help
If the stutter began with a specific game update, check the publisher's known-issues page;
frame pacing regressions are common after patches and are usually tracked publicly. If the whole
computer hitches, including the mouse pointer on the desktop, the cause sits outside the game and a
technician is better placed than a game support queue.
Where a paid option comes in
No purchase fixes frame pacing. Programs sold as game boosters mostly close background
tasks, which you can do yourself from Task Manager for nothing. Faster memory or a solid-state drive
helps with loading hitches specifically, and only when loading is demonstrably the cause.
What happens if my laptop becomes very hot while playing?
Short answerIt slows itself down on purpose. Processors reduce their speed once they reach a set temperature, which is why a laptop runs well for ten minutes and poorly afterwards.
What usually causes it
Laptops pull cool air through narrow vents and push warm air out of others. Dust mats the
fins behind those vents over a year or two, and a soft surface such as a bed or a lap blocks the
intake entirely. As the temperature rises, the processor and graphics chip reduce their clock speed to
stay within a safe range. Nothing is broken, and the slowdown is the protection working.
Power settings have the same effect without the heat. A laptop set to a battery-saving profile, or
running on battery at all, may cap performance well below what it can do with the charger connected.
What to try first, at no cost
- Play on a hard, flat surface so the intake vents underneath are clear.
- Connect the charger and set the power mode to best performance while you play.
- Clear dust from the vents with short bursts of compressed air, with the laptop switched off.
- Raise the back of the laptop slightly so air moves under it.
- Lower the frame rate limit. A machine asked to draw fewer frames makes less heat.
- Check whether the slowdown tracks the fan noise. If performance drops as the fans reach full speed, heat is the cause.
When to ask for official help
A laptop that shuts down suddenly, smells hot or has a fan that no longer spins needs a
repair technician rather than a settings change. If it is within warranty, speak to the manufacturer
before opening it, since a self-service clean can affect that cover. The Australian Consumer Law gives
you rights beyond the manufacturer's own warranty period, and the
ACCC explains what those rights are.
Where a paid option comes in
A cooling pad can help a little on a laptop with underside intakes, and a professional clean
and repaste helps a great deal on an older machine. Neither is worth buying before the free steps have
shown that heat is the limit.
How do I tell whether my settings or my hardware is the limit?
Short answerChange one setting at a time and watch what moves. If dropping the resolution improves things sharply, the graphics chip is the limit; if it changes almost nothing, the limit is elsewhere.
What usually causes it
Every game divides its work between the processor, which decides what exists, and the graphics
chip, which draws it. Resolution and visual effects load the graphics chip. The number of objects on
screen, the physics and the game's own logic load the processor. When people describe a computer as
too slow, they usually mean one of those two is saturated while the other is idle.
Memory makes a third case. A machine short of memory pushes data onto the drive, and the symptom is
not a low frame rate but long pauses and slow loading.
What to try first, at no cost
- Set the resolution one step lower and note the change. A large improvement points to the graphics chip.
- Return the resolution and instead lower shadows, reflections and anti-aliasing. These are graphics work too, and cheaper to give up.
- Reduce the view distance and crowd or object density. These load the processor, so an improvement here points there.
- Open Task Manager on Windows, or Activity Monitor on a Mac, while playing in a window, and see which component sits near its limit.
- Watch memory use during a long session. Steadily climbing use with growing pauses points to memory rather than speed.
When to ask for official help
The publisher's recommended requirements tell you what settings the game was built around.
If your parts exceed those and performance is still poor, that is worth reporting to the publisher,
because it suggests a fault rather than a limit.
Where a paid option comes in
Once the free tests point clearly at one component, an upgrade becomes a reasonable thought
rather than a guess. Buying before testing is how people end up with a faster graphics card in a
machine whose real limit was eight gigabytes of memory.
Why did performance get worse after an update?
Short answerEither the update added work your settings have not accounted for, or it reset settings, or a new graphics driver and the new game version disagree. All three are addressed without spending anything.
What usually causes it
Updates change what the game draws. New effects are often turned on by default, and a quality
preset you chose months ago may have been reset to the game's own idea of a sensible default. Shader
caches are also cleared by updates, so the first session after a patch includes compilation work that
will not repeat.
Driver timing matters as well. A game updated to use a newer graphics feature can perform poorly on
an older driver, and occasionally a brand new driver performs worse in one particular game until the
next release.
What to try first, at no cost
- Open the graphics settings and check whether your preset and resolution survived the update.
- Play two or three sessions before judging, so shader compilation is behind you.
- Update the graphics driver, or if the problem started with a driver, install the previous version instead.
- Clear the game's shader cache if the launcher offers that option.
- Turn off any newly added effect one at a time and note which one is expensive on your machine.
When to ask for official help
Performance regressions after a patch are tracked by publishers and discussed on their
support pages. Check there before changing hardware. If the game is unplayable after an update,
reporting it with your component details genuinely helps, because publishers prioritise by the
configurations that report problems.
Where a paid option comes in
Nothing here calls for a purchase. A patch that made a game slower on your machine is a
software problem, and buying hardware to absorb it is the most expensive possible response to a
problem that may be fixed in the next patch.
Do other open programs really make a difference?
Short answerSome do, considerably. Browsers with many tabs, recording software, cloud sync and anything that overlays the screen compete for exactly the resources the game needs.
What usually causes it
A game wants the processor's attention in predictable slices. A browser rendering video in a
background tab, a cloud service uploading a folder, or a backup starting on schedule all take slices
back, and the effect appears as the occasional long frame rather than a lower average. Recording and
streaming software is the heaviest of these because it encodes video continuously while you play.
Memory is the other half. Several heavy programs open at once can push the machine into using the
drive as overflow, which turns a smooth session into a stuttering one without changing the frame rate
counter much at all.
What to try first, at no cost
- Close the browser entirely rather than minimising it, then test.
- Pause cloud sync and scheduled backups for the length of a session.
- Turn off recording and streaming software unless you are deliberately using it.
- Check which programs start automatically with the computer and disable the ones you do not need.
- Schedule security scans for a time when you are not playing.
When to ask for official help
If you cannot find what is using the machine, Task Manager on Windows and Activity Monitor
on a Mac will name it. Where the culprit is software installed by an employer or a school on a managed
device, the people who manage it are the ones who can change it.
Where a paid option comes in
This is the problem that booster programs claim to solve, and what they do is close background
tasks on your behalf. You can do the same from tools already on the computer, and you will know what
was closed and why.
Is my second monitor or high refresh rate screen involved?
Short answerIt can be. Screens running at different refresh rates, or a cable that cannot carry the rate the screen supports, both produce symptoms that look like poor game performance.
What usually causes it
A computer driving two screens at different refresh rates has to reconcile them, and on some
systems that produces stutter in full-screen games. A more common problem is a screen advertised at a
high refresh rate that is still running at 60 Hz because nobody changed the display setting after
plugging it in, or because the cable supplied in the box cannot carry more.
Content on the second screen matters too. A video playing beside the game keeps the graphics chip
busy with work unrelated to the game.
What to try first, at no cost
- Open the display settings and confirm the refresh rate each screen is actually running at.
- Set both screens to the same refresh rate as a test, then try the game again.
- Use the cable type the monitor maker specifies for its highest rate rather than whichever one was to hand.
- Unplug the second screen for one session to see whether the problem disappears.
- Close video and animation on the second screen while playing.
When to ask for official help
The monitor manufacturer's specification page states which cable and which port carry the
screen's highest refresh rate. That page is the authority, not the general advice of a retailer.
Where a paid option comes in
If the cable is the limit, a correct cable is a small and genuinely useful purchase. Beyond
that, no software sold for this does anything the display settings do not already do for nothing.
Where the time actually goes
Which component each common graphics setting loads most
| Setting | Mostly loads | Worth lowering first? |
|---|
| Resolution | Graphics chip | Yes, the single largest effect |
| Shadow quality | Graphics chip | Yes, often costly for little visible gain |
| Reflections | Graphics chip | Yes |
| Anti-aliasing | Graphics chip | Yes, one step at a time |
| Texture quality | Graphics memory | Only if memory is short |
| View distance | Processor | Yes, when the processor is the limit |
| Object or crowd density | Processor | Yes, in busy scenes |
| Vertical sync | Frame timing | Test both settings rather than assuming |
Change one line at a time and keep the ones that help. A preset moves eight settings at once and
tells you nothing about which of them mattered on your machine.
