I just completed a new PC build that I thought would be a significant upgrade over my previous setup from 2023. I'm hoping to play games like Rust with my son, but I've been shocked by the performance. My old build had an Intel i9-14900KF and an RTX 4090, and it delivered over 100 FPS on the same servers I'm testing now.
The new build features an Intel Core Ultra 9 285K and an RTX 5090, but I'm struggling to hit 70 FPS even after optimizations. I noticed heavy stuttering while playing, especially when switching items in the hotbar or getting shot. My CPU usage was around 53% and GPU usage just 32%, which seems low for such powerful hardware. Did I mess up with the CPU choice or do I need to check something else?

You should definitely double-check your Nvidia drivers since bugs can cause massive drops in performance. Also, verify that your graphics settings are consistent with your old build, as auto-optimizations can occasionally misconfigure things. Lastly, don’t forget to update your motherboard’s BIOS, as running an outdated version can introduce problems.
Have you tried testing performance in other games or benchmarks to see if it’s just Rust that’s lagging? Sometimes, the issue isn't with your hardware, but rather how well it handles specific games. Also, make sure your GPU is properly seated in the PCIe slot and check CPU cooling. Low GPU utilization suggests something might not be set up right, so you may also want to consider reinstalling Windows if you suspect issues with bloatware.
It looks like your RAM speed might be a bottleneck, especially with the Core Ultra chips requiring faster RAM to unleash their gaming potential. Ideally, you want RAM rated around 7200 MHz for optimal performance. Though switching to Intel for a gaming rig might’ve been a questionable choice, considering Rust’s RAM sensitivity, it’s a rough spot to be in if it’s affecting your gaming experience.
