I have an asus gtx 770 with the nvidia 372.90 driver installed. I am having a problem where the frame rate is dropping to 19.90 (always that number) despite changing around the performance settings. It is very irradic in nature, and happens sometimes 5 minutes into the sim while sitting on the runway, and just now happened in the middle of my flight (had low 40s frame rates before the issue). I noticed the problem right after 10.50, but I guess I have updated my driver several times before I used xplane, so wan't sure.Thanks
Update: It seems after playing around with it a bit, and running GPU-Z that the likely culprit is that I am running out of VRAM. It seems that 10.50 is much more resource intensive to run than previous versions of version 10 ?
