I’m reviewing my hardware setup – an i7 8700 GTX 1080 Ti with 2 x 16 GB CAS and 15 3200 MHZ RAM (Crucial RAM). I usually run some older titles and wondered why I’m not seeing high FPS. It’s not too bothersome, as long as I can still play the games I like, no matter the settings. I’ve noticed through MSI After Burner that my GPU isn’t being used efficiently, only about 20–30% of it is active. In Skyrim I’ve set frame caps and seen better utilization, but other games show only around 30% usage. This pattern appears across many titles. GPU usage typically stays between 30% and 50% most of the time, especially in older games. It’s not a major issue, but I’m curious about the reasons behind it. Also, I’m playing at 2k 144Hz with GSync enabled.
It might be worth increasing your card usage. Check the GPU utilization using the heaven benchmark. Good luck!
Are you monitoring your task manager? Is the game running on a single thread? That’s likely, unless you’re using CPU affinity to direct it to one thread or two. It might just be related to the game engine itself. Check your frame rate in an older Source title like Half-Life 2—they typically have no strict FPS caps.
It seems the issue is probably related to the game engine, as older games rarely used more than 50% of their components.
Modern CPU usage metrics don't always reflect bottlenecks accurately. This happens because apps might not have enough threads available for processing. For instance, if an app only has four threads ready, it might seem 50% utilization on an 8-core processor. However, if each core isn't performing well, efficiency drops. Also, Windows assigns threads to any free core, adjusting based on optimizations like those in Bulldozer or Ryzen. Utilization is measured over a second, which can change rapidly if you translate it to CPU time. In older games, thread availability was limited due to synchronous programming, and performance limits often existed—such as Space Cadet 3D Pinball capping at 120 FPS on Windows XP to prevent CPU overload.
