Game frame rate decreases significantly after extended play sessions.
Game frame rate decreases significantly after extended play sessions.
Hello,
The issue occurs when I initiate any game, resulting in consistent 138 fps performance. This remains stable for approximately two to three hours of gameplay, after which fps drops to 110 and fluctuates between 110 and 120. Regardless of playtime, restarting the game instantly restores fps to 138, and the problem recurs after another two to three hours. Previously, I experienced a similar issue that resolved itself with disabling Superfetch in Windows 10, although it reduced the fps drop duration and lowered the severity. I suspect a caching mechanism where my PC collects game data, subsequently utilizing this cache for slower performance and reduced fps. I lack further insights as restarting the game after six hours or more results in a temporary return of stable fps for several hours, seemingly indicating the PC clears and slowly regenerates its cache. I have attempted using memory standby without success, and my 32gb RAM remains largely unutilized (around 30% full). Temperatures are consistently stable at 60c for the GPU and 55c for the CPU. Please suggest solutions to resolve this persistent fps drop issue.

GPU 1080ti

Did the pagefile experience a modification before being reverted to automatic? If so, what was its previous setting?
If you plan to adjust the pagefile size, consider using the settings depicted in the image on the C:\ drive of your operating system.
Determine the size of your OS drive and assess the remaining free space on it. Maintain at least 20% free space to prevent potential performance issues.
If Game Bar is active, ensure that capture functionality is disabled and gameplay recording is not initiated.
Reduce the pagefile size, starting with a 1GB initial limit and a maximum of 10GB. Monitor the pagefile's growth to assess its impact on performance. Your system is capable, and it’s conceivable that Windows' pagefile management is contributing to performance degradation.
Has the pagefile been modified previously? If so, what was its setting?
If you intend to adjust the pagefile size, refer to the settings depicted in the image for the OS C:\ drive.
Determine the capacity of the OS drive and the remaining available space on it. Maintain at least 20% free space to prevent performance issues.
If the Game Bar is active, ensure that screen capture features are disabled and game recording is turned off.
Tested with no page file / 1024+10240 / 1024+1024 – automatic testing showed no difference. I also tested FPS drops in several games over a prolonged period (6+ hours of gameplay) to observe how the drops appeared. I began games with stable 144 fps, and a slight fluctuation of 1+- fps remained consistent. Over the next hour, FPS decreased to 138-144, and then further to 130-138 fps over the subsequent 30 minutes, consistently dropping. The lowest FPS I recorded before stopping was jumps of 85-100 fps after 6 hours. Restarting the game immediately restored normal FPS, and the process repeated identically. Temperatures were consistently between 50-55 degrees Celsius during gameplay (GPU/CPU, etc.). RAM usage never exceeded 30%, and CPU and GPU loads were variable depending on the game, but the issue persisted even when both GPU/CPU loads were 30-40% (in indie games). It is frustrating, and I’m unsure of the cause.
I have just noticed one thing and am going to test it. It’s possible that when I experience FPS drops, my GPU downclocks to a lower clock speed (around 1400 or similar) – it’s overclocked up to 1911MHz and works stably with all tests. I don’t understand why the GPU is downclocking after an hour, even if it isn’t overheating or exceeding power limits. I will check this.
This presents a challenge, as performance degradation like this often stems from overheating, throttling, excessive pagefile usage, or insufficient space for TRIM operations. None of these factors appear to be present in this situation. I’m somewhat perplexed. Experiment with the graphics card; an overclock may be the cause. Consider reducing the clock speed to test if a stock configuration resolves the issue.
