Upgraded from Gtx 770 to Nitro rx480. (Big performance improvement in P3d v3.4.)
[ I7 980 - rampage formula 3 + 24gb - ssd drives x 2 - win 10 x 64]
X-plane 10.51 and x-plane 11b13 do not like the Nitro.
On screen fps meter: (actual 13, in sim 19). Does not help if I turn down the graphics settings to bare minimums. I get no increase in frame rates whatsoever. I am a P3d convert as of x-plane 10.
In order to enjoy the x-plane experience I reinstalled my 770. Waiting for the day that I can put the Nitro back in my machine. BTW: the rendering of textures etc seems so much sharper vibrant when using the Nitro.
