Xplane 11 bug

Featured Replies

Hey guys so recently my XP11 Was facing a fps issue. For example i get about 70 fps in xp and every like half a second it drops down to 20 so it happens all the time and the game feels like fluctuated so i was wondering if i can find help from someone.

Thanks!

I did reinstall XP11 and my graphics card but it still doesnt seem to work.

Check your antivirus settings and exclude XP from routine scanning.

Would be important to know if you're in OpenGL or have opted for Vulkan in the game settings ? It can make a good difference, depending on your system specs.

If possible, give "Vulkan" a try by enabling it and then restarting XP11.53.

This would be the first place I would check.

Strange indeed ... Another shot - turn hyperthreading  OFF in your Mobo if you can, and then check again.

I believe it was said that the latest versions of XP11 were neutral to this, but the first versions did suffer in performance from havinh HT on ( I believe it is called differently in AMD parlance ? )

I tried that too it's not working. Fsx runs perfectly fine when i play it even xp used to run very well before but im not sure what happened tho. This happened to me last year i simply reinstalled my Graphics driver and everything was fixed and i reinstalling my graphic card when this happened hoping it would be fixed nothing happened. 

Does your PC have an inboard Graphics Card ? If so could it be the case that XP11 is using the onboard GC instead of the correct card ?

In what Windows version are you ?  If XP10, is an upgrade to XP11 possible in your case ? In my case I gained in performance and am satisfied with Win 11.
