Question RTX 4090 Way Too Low FPS In All Games

Sep 17, 2023
I just built a PC and I'm getting way lower FPS than benchmark videos on YouTube.

For example, in RDR2 at 1440p I'm getting between 50-70 FPS on Ultra, while all YouTubers are getting 110+ FPS running the same exact settings. Some games hit much higher (100+) FPS, but overall still less than expected in comparison to others with similar rigs.

I'm on a new fresh installation of Windows. All drivers and BIOS firmware are up to date, I also tried using DDU to uninstall and reinstall the Nvidia driver, and I tried rolling back to an older version. DHCP enabled in BIOS.

3DMark Basic gave me a 29464 score, with a CPU score of 14972 and a graphics score of 35535. It seems to match online scores. I'm not sure why my games are getting much lower FPS then.

During GPU-Z bus interface render test, it keeps going from PCIe x16 4.0 @ PCIe x16 4.0 to PCIe x16 4.0 @ PCIe x16 2.0. When inside RDR2, it's constantly PCIe x16 4.0 @ PCIe x16 4.0 and doesn't change. My total CPU utilization averages around 15% in RDR2, and 100% GPU usage. One thing I noticed is that GPU wattage barely reaches 390w at maximum load, even though I know this card easily runs around 450w. I don't have any BIOS or software modifications that would limit the GPU capabilities though.

saw your post on reddit

can you run another benchmark which is able to run above 60fps?
3d mark can run below 60fps and still give nice score numbers

try unigine superposition, even at 8k it is able to run above 60fps with your gpu

you probably have 1440p monitor, so pick 1080p extreme preset
Thank you for your reply.
Here are my results (it's showing Win10 for some reason even though I'm on 11)
