Need assistance with FPS on a Ryzen? Let me know how I can help!
I recently assembled a new PC with a Ryzen 5 1600, 16GB DDR4 2400 GTX 1070, Windows 10 Pro. My problem is that in certain games I experience very low FPS. It seems the game is running on just one thread, not all at once—only a few titles like Portal 2 and Rocket League seem to handle it well. I’ve attached some screenshots showing my CPU and GPU usage, multi-core rendering enabled, and a task manager display indicating only one thread is at its limit. My lower-end build still manages 4K without issues. Anyone know what might be causing this or how to resolve it?
Uncertain about the solution, aside from a quick thought: 4K cuts CPU demands.
A higher resolution reduces the amount of CPU work by producing more detailed images with fewer pixels, which lessens the processing demands.
It's not a CPU problem. The CPU is more than able, and it seems there isn't any bottleneck. When gaming, GPU usage appears to be the main concern. It might be related to the GPU driver or temperatures. If you can't see the details while playing on a single screen, try software that records longer graphs—such as Aida64, HWmonitor, OpenHardwareMonitor, or MSI Afterburner.
They suggest there’s minimal additional strain on the CPU with higher resolution settings. It doesn’t necessarily lower CPU usage, but it can make a difference. I noticed this when using my GTX 1070 with the FX-8150—Fallout 4 ran smoother in 4K compared to 1080p since the GPU was handling more work.
The CPU appears to operate on just one core, isn't that a problem?
The first image displays CPU in the upper left with temperature, CPU utilization on GPU, and GPU frame rate. Temperatures and loads appear high. The second image reveals one thread reaching maximum capacity while the remaining eleven remain almost idle.
It seems many games run smoothly on single-core setups. GPU performance should exceed 70%, ideally surpassing 90% with minimal CPU involvement to avoid bottlenecks. This points toward a driver problem. Consider running benchmarks to check if the GPU can hit 100%. If CPU struggles, it might be pinned at over 80% while GPU stays under 30%. I don’t own Portal 2, so direct testing isn’t possible. On RL, I see around 40% usage on one core and 70% GPU load.
Yes, I can reach full GPU utilization. As mentioned earlier, this isn't available in every game. On my FX setup, I achieve over 600-700 FPS in Portal 2 with all cores active, and in Fallout 4 I run at 1440p using maximum settings. The GPU stays around 75-90% usage, capping at 60 FPS, while the CPU rarely exceeds 50%. Interestingly, Portal 2 and Rocket League seem limited to a single thread on my new Ryzen system.
