You're experiencing performance unevenness where one CPU core stays heavily loaded while others idle, and your GPU maintains a stable usage range. This suggests the CPU might be the bottleneck limiting overall frame rates.

I tried doom and found my cores averaged around 50-70% each, while the GPU performance stayed at 97-99%.

Top processor and graphics card installed on a five-year-old game. Need a full spec list.

The performance remains steady across various displays and configurations. Since the output isn't at full resolution, potential bottlenecks shouldn't arise. EDIT NMS has consistently required a lot of processing power, so it might be worth checking if your current settings are ideal.

I've also tested Minecraft with RTX and the CPUs are about 20-50% usage, while the GPU runs at 60-75%. -Specs Overview - CPU: i5-12400F GPU: Rtx 4070 RAM: 32GB DDR4 3200MHz Memory: b660 Aorus Master DDR4 PSU: 850W Evga Platinum. Resolution: 1440p Settings: Ultra

FPS appears to be the key element missing here...GPU and CPU usage (best to track both the peak single-core percentage and overall usage) along with FPS. I don’t have personal experience with these titles, but several factors could be at play: outdated game engine → poorly optimized code → Nvidia global settings versus game settings conflict, or frame limits in either case. Alternatively, a cap on frames on either side → (I remember another scenario, but it’s fuzzy). If you use DSR/DLDSR (like with a 4070 and 4k render → 1440p downscale AA), I’d suggest verifying that scaling doesn’t interfere or override the game settings. Enabling DLSS will completely take precedence over downscaling, giving higher resolution even with lower usage, but you’ll still want low CPU/GPU load to maintain decent FPS. Thanks to Nvidia Experience for the 'Optimize' tip!

I tried my version of NMS on a 34-inch IPS 3440 1440p at 144Hz. I adjusted the settings to Ultra and fixed the frame rate at 144 in Space, which stayed steady. Moving through planets caused slight fluctuations between 120 and 144fps, with drops to around 80fps when things slowed down. Switching back to High mode made a big difference, showing almost no change in FPS. I'm pairing it with a 3080 10GB LHR and an AMD 5900x.

People often play Doom to evaluate FPS performance. Also, try downloading Warzone 2.0, Apex Legend, PUBG, and see how they perform there.
