Minimal GPU consumption
Minimal GPU consumption
I upgraded to a Ryzen 5 2600 with 3.4GHz, 16GB DDR4, and an Intel B450M processor. It runs on Gigabyte B450M DS3H V2 XR8 with an 80+ Bronze Corsair Ice Airflow case. The system includes a 512GB SSD, stock cooler, and 450W EVGA graphics. Recently I bought an RTX 2060 for gaming upgrades. Previously I used an Intel Core i5-1650. Now I notice performance drops—4K runs at 40 FPS max, 1440p at 70-100 FPS, 1080p at 60-100 FPS, and 49% load. When benchmarking with KSI Kombuster, everything stays stable and loads consistently. This seems normal for the current settings.
The guideline suggests that lower resolution means increased CPU usage and decreased GPU usage, while higher resolution correlates with reduced CPU load and higher GPU activity. Your findings seem reasonable, but could you confirm if this aligns with your expectations?
I wasn't the top PC expert, so I'm here because I think you could get more value from it at 1080p. It doesn’t seem to be handling it well, though. Also, I didn’t mention that when optimized for 1080p, the load stays between 35 and 45—still seems normal.
Looks like you want higher frame rates at 1080p compared to 1440p when it's already capped at 1440p.
My CPU usage matched the GPU usage, and it never exceeded 50%.
Several elements influence your frame rate. Make sure you test at the same spot in the game and keep all other settings the same, except for the resolution.
I looked into further and the main options were reinstalling or updating the GPU BIOS, but I’m unsure where to start.
Rust performs best on single-core systems due to its IPC constraints, which restrict scaling across multiple cores for GPU efficiency. The performance in 1-4 threaded scenarios often depends on the game logic rather than the game itself. Try different titles during troubleshooting to confirm whether your hardware is the problem.
