Table of Contents
Most performance advice online is either obvious or useless. This list is neither. Every item below is free, takes minutes, and produces a measurable difference on a typical machine.
1. Use launch options
This sits at the top because it is the most powerful thing on the list and the one fewest people know about.
Many games accept parameters passed to them before they load, controlling decisions the settings menu cannot reach — which rendering path is used, how many processor threads are allocated, whether startup sequences are skipped. Because they apply during initialisation, they influence choices that cannot be changed once the game is running.
The specifics differ per title, and community documentation is thorough. Anyone playing competitively will find detailed writeups of the best cs2 launch options explaining what each parameter does. Add them one at a time and test after each — pasting a long list from a forum is how people end up with a game that will not start.
2. Check your monitor is actually running at full speed
A surprising number of people buy a fast monitor and never enable it. Windows frequently defaults to a lower refresh rate, and nothing tells you.
Open display settings, find advanced display, and confirm the refresh rate is set to the maximum your monitor supports. This takes thirty seconds and is the single most common wasted upgrade.
3. Kill the overlays
Chat applications, storefronts, recording software and graphics utilities all inject overlays into games. Each one adds a small cost, and people typically run three or four simultaneously without noticing.
Disable them individually in each application’s settings rather than uninstalling anything. The functionality you actually use is rarely the overlay.
4. Set the power plan properly
Laptops especially ship configured to save battery, which deliberately limits performance. Set the power mode to high performance and keep the machine plugged in while playing.
On some laptops this alone doubles what the hardware delivers, which is a startling return for a setting most people never open.
5. Clean the dust
The least technical item and one of the most effective on any machine over two years old.
Dust accumulates in fans and heatsinks, temperatures rise, and the hardware automatically reduces its own speed to avoid overheating. The performance loss is gradual enough that most people adapt to it without noticing.
Compressed air, ten minutes, once or twice a year. On an older laptop the improvement can be dramatic.
6. Use a cable, not Wi-Fi
Wireless connections have improved enormously, but they remain more variable than a wired one. For competitive play, variability is the problem — not average speed.
An ethernet cable removes an entire category of unpredictable behaviour. If running one is impractical, at least ensure the router is on a modern band and nothing large is streaming while you play.
7. Cut shadows and anti-aliasing first
Graphics settings do not cost equally. Shadow quality and anti-aliasing consume a disproportionate share of the budget while contributing little to how well you actually play.
Drop those two before touching anything else. Texture quality, which people often reduce first, depends mainly on available graphics memory and is frequently cheap.
8. Update your graphics drivers from the source
Download drivers directly from the manufacturer rather than relying on automatic system updates, which lag behind. Driver releases often include genuine optimisation for specific titles, particularly newer ones.
9. Raise your mouse polling rate
Most gaming mice support higher polling rates than they ship with. The setting lives in the manufacturer’s software and determines how often the mouse reports its position.
The improvement is small but real, and it costs nothing. While in there, disable any acceleration or smoothing — consistency matters more than raw speed for aim.
10. Leave your drive some room
A drive that is close to full slows down measurably. Aim to keep ten to fifteen per cent free.
If the machine has both a solid-state drive and a conventional hard drive, make sure games are installed on the faster one. This mainly affects loading times, but the difference is immediate.
The honest summary
Work through this list before considering an upgrade. A machine running default settings with four overlays active, a throttled power plan and a monitor at half its refresh rate is not showing you what it can do.
Plenty of people convinced they needed a new computer discovered they needed an afternoon instead.
