Low FPS, CPU and GPU not fully utilized

Question

My system is:

- i7 4790k 4.7ghz watercooled at 60° full load
- Geforce GTX 1080ti
- 16GB RAM

In VR I get 20 fps but I see my GPU and CPU are not under full load. Why are my frames low when apparently my CPU and GPU still have some mussle left?

Answer 1

Your RAM is fine, you don't need more and RAM won't give you a performance boost. Turn off threaded optimization in nvidia control panel settings.

Answer 2

Hi Servaas Dejaegher

I'm not with Laminar Research, just a fellow simmer in the UK, but generally speaking, your CPU & GPU specs (being the most important hardware considerations) look great and should be well capable of managing X-Plane 11 software. The RAM on the other hand is on the low side, 32GB > would be better.

I'm not running VR, but I have a similar spec to you with 64GB RAM & two monitors and I'm currently getting over 60 fps, but that's with X-Plane 11.25!

If you're running version 11.30, then other simmers have reported similar issues, so you may need to file a bug report to LR accordingly?
