PC gaming FAQ.

Browser results can be affected by browser versions, background activity, thermals, power settings and hardware acceleration. Use the result as a comparative diagnostic rather than an exact game FPS measurement.

No. FrameForecast's PC benchmark is intended for desktop and laptop PCs. Mobile visitors are asked to open the benchmark on a PC.

Close heavy applications and downloads, use the intended power mode, allow the PC to reach a normal temperature and avoid changing settings between comparison runs.

The benchmark measures browser-side CPU, graphics, memory and frame-time performance. It is a diagnostic signal rather than a replacement for native in-game benchmarks.

A CPU bottleneck happens when the processor cannot prepare game work quickly enough for the GPU, limiting frame rate even when the graphics card has performance left.

Gaming CPUs benefit from strong per-core performance, sufficient cores and low memory latency. Some games are far more CPU-sensitive than others.

It can. CPU sockets and chipset support vary by processor generation. BIOS support, motherboard power delivery and RAM generation also need to be checked.

For visually demanding games and higher resolutions, GPU upgrades often have the larger effect. For high-refresh competitive gaming or CPU-heavy games, the CPU can matter more.

Higher resolutions increase the number of pixels the GPU must render. Moving from 1080p to 1440p or 4K therefore tends to increase GPU load and reduce FPS.

FPS is how many frames the PC produces each second. Refresh rate is how many times the monitor can update each second. The best experience comes from balancing both.

1% lows describe the slower frames in a gaming session and help show frame-time consistency. A high average FPS can still feel poor when lows are much weaker.

60 FPS is a strong baseline for smooth gaming. 120–165 FPS makes more sense with high-refresh monitors, while 240 FPS and above is mainly valuable in competitive games.

Low FPS can come from GPU limits, CPU limits, insufficient RAM, thermal throttling, background apps, drivers, game settings, resolution, or power-saving modes.

A GPU running near full utilisation while the CPU has headroom often indicates a GPU-heavy limit. Higher resolutions also tend to shift more load toward the graphics card.

Check card length, height and slot thickness against the case specifications. Radiators, front fans and drive cages can reduce the usable clearance.

Possibly. Check the GPU manufacturer's recommended power capacity, connector requirements, PSU quality and the power draw of the rest of the system before upgrading.

VRAM needs vary by game, resolution, texture quality and ray tracing. More demanding settings and higher resolutions generally increase video-memory requirements.

Start with the games, resolution, refresh rate and budget you target. Then check PSU capacity, power connectors, case clearance and whether the CPU can support the performance level.

DDR5 provides more bandwidth and is used by newer platforms, but changing from DDR4 can require a new motherboard and CPU platform rather than a simple RAM swap.

Using the correct matched memory configuration increases available memory bandwidth and can improve performance compared with a poorly configured single-channel setup.

16GB remains usable for many games, while 32GB gives more headroom for modern games, background applications and multitasking.

It can, particularly in CPU-limited situations. Capacity, memory channels, latency and CPU memory-controller behaviour matter alongside the advertised memory speed.

Higher-power processors can require stronger cooling to sustain boost performance. Check the CPU's cooling guidance, case clearance and the cooler's socket support.

Check CPU socket, chipset and BIOS support, RAM generation, expansion slots, storage interfaces and power-delivery capability before purchasing an upgrade.

A PSU should comfortably support expected system load and transient power spikes. Quality, age, connectors and manufacturer recommendations matter in addition to wattage.

Identify the component limiting the games and settings you actually use. GPU, CPU, RAM, storage, cooling and power requirements should be considered as a system rather than independently.
