I'm having a serious issue with my video games; I'm experiencing extremely low FPS, even in games I've played without problems before. For example, I used to have a minimum of 120 FPS in Dota 2, but now it's dropping to just 4-5 FPS in the main menu. Other games are managing only 10-20 FPS. Here are my specs:
- Intel i7-13620H
- Nvidia RTX 4060 (8GB)
- 32GB RAM
- Windows 11
I've also run LatencyMon and noticed high DPC latency with ACPI.sys and my graphics driver.
To troubleshoot, I've already tried several things:
- Updating my graphics card and Windows
- Uninstalling a problematic Windows security update (kb5074109)
- Completely uninstalling and reinstalling various Nvidia drivers using DDU
- Formatting Windows 11 from version 25h2 to 23h2
- Disabling all game overlays
- Optimizing drivers
- Switching between DX11 and Vulkan
- Adjusting graphics card settings
I've even noticed that the internal graphics perform better than the external, which suggests a possible issue with the external GPU. Before I send my computer in for service, what other tests can I run? Any fixes I might have missed? Thanks in advance!

Have you tried reseating the GPU? Sometimes just a loose connection can lead to seriously low performance. Also, if nothing else works, running OCCT tests for the CPU and RAM could help you figure out if it's actually your GPU that's the problem.
I know it’s super frustrating to deal with low FPS issues! You might want to turn off Intel XMP if that’s enabled; it can cause instability in some setups. And don’t forget, it can be beneficial to update your BIOS if there's a new version available.
You should definitely run some benchmarks like 3DMark and Supersposition to see if your FPS is also low there; if it is, there might be a hardware issue. While you're at it, use HWinfo64 to monitor your temps in the background and check for any thermal throttling.
Also, try switching your GPU to a different PCI-E slot. Sometimes, that can resolve the issue. If it improves your FPS, you might need a new motherboard.
Another tip is to swap out the PSU power cables for the GPU if you have some spares. Make sure each connection has its own cable instead of using one for multiple GPUs. Finally, reseat your GPU, and consider turning off XMP and resetting your BIOS to defaults. If there's a new BIOS version, updating it could also help.
To update your BIOS, check your motherboard's support page on the manufacturer's website. You should find the latest version there!
I did VRAM and 3D adaptive tests with OCCT and got no errors. Thanks for the suggestions! I'll run those benchmarks you mentioned.
