Xplane low fps and not using 100% of the gpu, i have AMD rx6700

[Nochi]

Hello, i've been playing this game since a long time, and I used to have a gtx 1050ti which gave me like 40 fps aprox. But when I changed to a new gpu to a rx6700, my fps is still the same, and I can see that my gpu don't use the 100% of the gpu.

My pc :

CPU: Intel core i7 -9700k 3.6GHz
GPU: AMD Rx6700
16 GB RAM

That's telling you that your CPU is what is limiting your fps (40fps for a flight sim is not bad by the way).
First thing: make sure that you have Vulcan enabled in your XP settings.
Then your options are to turn up some of the GPU-related graphic settings (e.g. texture quality, anti-aliasing) to max out your GPU at the same framerate, or dial down one or more of the CPU-related settings such as No. of world objects if you feel the need to up the fps. Personally, I'd be more than happy with 40 fps, especially if flying one of the more complex aircraft.
Final option would be to upgrade your cpu, but then you'd be into a new motherboard and a whole load of extra expense.

Launch XP11 and click "Settings". At the top left of screen click the circled question mark. Click on "XP11 Desktop Manual". You'll find everything you need here so save a copy and print what you need. The manual explains the demands on the cpu & gpu well so spend some time at the pilots' lounge with the desktop manual and get your briefing.
