I built or bought a PC with an Intel Core i7-14700F, 32GB of DDR5-5600 memory, an RTX 5060 Ti with 8GB of VRAM, and a 1440p 240Hz monitor. However, games such as Forza, Rocket League, and Fortnite feel noticeably uneven, with frequent microstutters despite the system producing good frame rates. I recently played at an internet café and immediately noticed how much smoother that PC felt, so I know this probably isn't just normal high-refresh-rate behavior. My previous system, which had a GTX 1650 Super and a 144Hz 1080p monitor, also seemed smoother. I've already tried reinstalling Windows, using DDU, changing BIOS, Windows, NVIDIA Control Panel, and registry settings, reseating the RAM and GPU, and various other troubleshooting steps. What should I check next, particularly regarding VRAM usage, frame-rate limits, memory settings, temperatures, clock speeds, and background processes?

The first thing I’d check is VRAM usage. At 1440p, 8GB can become a limitation in some modern games, especially with high textures or ray tracing. Once the card runs short on VRAM, it may start relying more heavily on system memory, which can cause stutters even when the average FPS looks good. Try lowering texture quality and ray tracing, then monitor VRAM usage while playing. Also test an FPS cap slightly below your monitor’s refresh rate instead of letting the frame rate fluctuate around 240 FPS.
Since you’ve already reinstalled Windows and used DDU, avoid changing random registry and driver settings for now and narrow it down with controlled tests. Try one game at reduced settings, a lower frame-rate cap, and lower textures. Then compare it with uncapped gameplay. If the frame-time spikes remain even at lower settings, the problem may be unrelated to GPU performance and could involve drivers, background software, memory stability, or the monitor’s sync configuration.
Use a monitoring overlay or logging tool to look at GPU and CPU temperatures, utilization, clock speeds, RAM usage, and VRAM usage while the stutters happen. Check whether the CPU or GPU is overheating or suddenly downclocking. It’s also worth confirming that your DDR5 is running at its intended speed with the appropriate memory profile enabled, and that no unnecessary applications, overlays, recording software, or browser tabs are running in the background. Frame-time graphs are more useful than average FPS here because they can reveal the spikes causing the choppy feeling.
Eight gigabytes is becoming a tight amount for a 1440p gaming card. Even if VRAM isn’t the only cause, lowering textures is a useful test because it can show whether the stuttering is memory-related.
