How to Optimize a Gaming PC for High Refresh Rates
To optimize a gaming PC for high refresh rates, confirm the monitor is using its intended Hz, measure a repeatable gameplay section, then reduce the workload that actually limits frame delivery. Use supported latency and synchronization settings, and choose a sustainable frame-rate target rather than chasing the largest counter reading.
I would make one change at a time and keep a short record. A 240Hz screen, 240 displayed FPS and responsive, consistently timed gameplay are related goals, but they are not interchangeable measurements.
01Confirm the display is ready for the target
In Windows 11, open Settings → System → Display → Advanced display. Select the gaming monitor and check its current resolution and refresh rate. Choose the supported rate you intend to use, then confirm it remains selected.
If the expected option is missing, check the monitor's input-specific capabilities, GPU output and cable. Our gaming monitor connection guide covers that signal path. Software tuning cannot make an unsupported connection mode appear.
Also inspect the game's display mode and selected monitor. Some games expose their own refresh setting in fullscreen mode. Establish the actual output before interpreting a performance counter, especially when a second display or laptop panel is present.
The intervals above explain why moving from a 60 FPS target to 240 FPS is demanding. Each complete frame must arrive much more frequently. CPU and GPU work can overlap, so do not simply add their reported timings and call the result the display interval.
02Record a useful baseline
Choose a short, repeatable route containing the busy scene where performance matters. Keep the game build, resolution, graphics preset and background workload consistent. Let loading and any explicitly indicated shader preparation finish before recording the comparison.
Note average FPS, frame-time behaviour and relevant CPU/GPU telemetry with one suitable tool. Intel PresentMon provides performance capture and a GPU Busy metric; Steam's performance monitor can also distinguish base and generated frame rates in supported cases. Read each metric's definition instead of assuming every overlay counts the same events.
For the first workload diagnosis, switch frame generation off where available and record any frame cap or synchronization limit. You can restore generation later. This makes it easier to see whether the engine is genuinely rendering faster after a change.
Repeat a promising change before keeping it. A single faster run can reflect a different scene, completed background work or a warmed cache. My deciding question is whether the demanding section improves consistently without an unacceptable visual or responsiveness trade-off.
03Find the limit before lowering everything
A CPU limit and a GPU limit need different responses. The CPU handles game logic and submits rendering work; the GPU executes graphics work. The balance can change across scenes, so a quiet room is a weak proxy for a crowded match or busy city.
Try a lower render scale or resolution in the same scene while keeping CPU-heavy options unchanged. A substantial FPS increase points toward graphics workload being important. Little change makes a cap, CPU or engine restriction, or another bottleneck worth checking.
Utilization supports that investigation; it does not replace it. A frame cap can leave the GPU below full use, and a total CPU percentage can hide a busy critical thread. Do not diagnose a broken processor from one percentage or buy an upgrade from a generic bottleneck score.
Compare render scale, demanding lighting and ray-tracing settings separately. Keep the changes that improve the same scene while preserving acceptable image quality.
Check caps and compare settings such as simulation detail, crowd density or draw distance where the game exposes them. Which settings affect CPU work depends on the engine.
I would not reduce every option at once. It can make the picture worse while leaving the actual limitation unchanged, and it removes the evidence needed to choose the next adjustment.
04Use upscaling and frame generation for different jobs
A supported upscaler can reduce the internal rendering workload while reconstructing the chosen output resolution. Start with a quality-oriented mode, compare the same scene, and move to a lower input resolution only if the result remains visually acceptable and helps the target.
Check detail during motion, not only in screenshots. Thin objects, disoccluded areas and moving effects can reveal compromises that an average FPS figure misses. If lowering render scale barely changes performance, a more aggressive scaling mode may not address the limiting work.
Frame generation adds intermediate images to the displayed stream. It does not make game simulation or input sampling run at the larger displayed-FPS number. Improve the base cadence first, then compare generation for smoothness, artifacts and control response.
Feature support is specific to the GPU and implementation. Vimessa's DLSS feature support guide explains why an RTX 30 card can support reconstruction features without official NVIDIA Frame Generation support. A newer suite name is not permission to enable every feature.
For competitive play, I would judge base performance and input feel first. For visually demanding single-player games, generation can be worth comparing once the underlying game is responsive enough. Neither choice needs an invented universal minimum FPS.
05Reduce latency with supported game controls
On a compatible NVIDIA setup, enable the game's Reflex option and compare its supported modes. Reflex coordinates CPU and GPU work to reduce latency; it is not a promise of higher average FPS. NVIDIA's system latency guide explains the distinction and why Reflex takes precedence over driver Ultra Low Latency functionality when both are enabled.
On supported Radeon hardware and games, compare the game-integrated Anti-Lag 2 option where available. AMD documents its role in reducing latency in GPU-bound situations. Availability requires the appropriate hardware, driver and developer integration; it is not a universal switch for every game.
My recommendation is to start with the game's supported latency control before adding driver or external layers. Record the change and test the same movement or aiming sequence. Keep the option when its behaviour suits your setup instead of assuming every toggle provides an additive benefit.
If the complaint is online rubber-banding or delayed server response, investigate network behaviour separately. A faster local frame rate and lower rendering latency do not establish that the connection to the game server has improved.
06Choose a synchronization strategy deliberately
Variable refresh rate, or VRR, allows a compatible monitor to adjust refresh timing within a supported range. V-Sync controls presentation relative to display refresh. Your preferred combination depends on whether you prioritize tear-free output, minimum latency, or a balance between them.
| Priority | What to compare |
|---|---|
| Lowest latency; tearing acceptable | Supported latency control with V-Sync off; assess uncapped behaviour and GPU load. |
| Tear-free VRR play | The game's documented VRR, V-Sync and latency-control combination; check its automatic limit. |
| Consistent sustainable output | One compatible limit at a rate the demanding section can maintain. |
| Frame generation enabled | Integration-specific guidance and a clear distinction between base and displayed FPS. |
NVIDIA describes G-SYNC with V-Sync and Reflex as a supported route to an automatic below-refresh limit. Valve also recommends that combination for compatible CS2 configurations. Keep that recommendation attached to the supported setup; do not translate it into a rule for every GPU and display.
If the automatic setup already holds output at the intended ceiling, another manual cap may add nothing. When a manual limit is needed, verify what it controls and whether it overshoots. The sister site's frame generation caps guide covers why one fixed subtraction from refresh rate does not fit every integration.
A cap sets a ceiling; it cannot lift a low frame rate. If a demanding section repeatedly falls below the target, improve the workload or compare a lower sustainable target. Avoid several unrelated manual limiters while establishing the baseline.
07Check Windows presentation and background work
For compatible DirectX 10 and DirectX 11 games in windowed or borderless mode, Windows 11 offers Optimizations for windowed games. It moves compatible games to a newer presentation model, reducing frame latency and enabling supported features such as VRR.
Find it under Settings → System → Display → Graphics, then restart the game after changing it. If a particular title develops a problem, use its per-app graphics options to compare the setting off. Do not assume exclusive fullscreen is always faster on every current Windows configuration.
Close unnecessary background workloads for a controlled test: a video encode, active download, browser animation or recording session can make two runs incomparable. Keep the software you actually need, then test its cost separately if the target remains out of reach.
Update a game or driver when its documented fixes are relevant, and record the installed version. If performance changed after an update, compare that event with the symptoms before making unrelated changes. A stable, explainable configuration is more useful than changing every available setting between runs.
08Check sustained performance and monitor response
Compare the beginning of a session with the point where performance gets worse. Record temperature, clocks and any reported throttling status alongside the workload. A momentary temperature peak alone is not enough to diagnose a cooling failure.
If sustained throttling is confirmed, check the exact processor or system maker's cooling guidance, airflow and installation requirements. Keep normal protections in place while diagnosing it. There is no single temperature limit that applies to every CPU and GPU.
Monitor overdrive adjusts pixel transitions and is a separate control from rendering FPS. Start with a moderate documented setting and inspect movement for overshoot or distracting trails. The strongest setting is not automatically the clearest choice across the display's refresh range.
I would establish stable stock behaviour before considering manual tuning or hardware replacement. If the machine cannot meet the target after relevant adjustments, compare the component that limits the workload rather than upgrading by model-name prestige.
09Frequently asked questions
Must FPS exactly match the monitor's Hz?
No. A suitable VRR setup can accommodate output within its supported range, while competitive players may accept tearing for another latency trade-off. Choose and verify a presentation strategy rather than chasing equality between two numbers.
Is 100% GPU usage automatically bad?
No. It can be normal under a demanding graphics workload. Read it alongside frame time, active limits and responsiveness. The useful question is whether the configuration meets your target.
Will frame generation make 120 FPS feel like native 240 FPS?
Do not assume that. Generated output and the rate of new game simulation are different. Compare actual control response and image quality instead of treating a doubled counter as equivalent native performance.
Can settings changes guarantee 360 FPS?
No. The game engine, scene, CPU, GPU and chosen image quality set practical limits. If the target remains out of reach after useful changes, compare a lower sustainable target or a hardware upgrade justified by the measured workload.
10Keep the result you can reproduce
Save the final display mode, graphics settings, latency option, synchronization strategy and active limiter. Repeat the original demanding route and compare consistency, image quality and responsiveness with the baseline.
My preference is the highest useful performance the game can deliver consistently with acceptable visuals and input feel. Keep changes that demonstrate that benefit, restore changes that do not, and let the evidence decide whether any hardware upgrade is necessary.
