First time I've done this so hope it's ok.
Flying on VA server the screen starts to stutter, getting worse very quickly to a point where it stays fixed - like a screenshot, and game locks up. I was getting around 60 fps prior to crash. There were others on the server that were warping.
Only way to get a response is to exit game from task manager, which states DCS not responding. Same crash has happened several times now, but not on a regular basis.
I am currently using Mustang's ground texture mod from the 104th however I was getting this same crash before installing the mod so not the cause I think.
Currently using Nvidia Geforce 364.51 GPU drivers.
EDIT
Just noticed I have posted this in open beta forum, my mistake gents, I was on the 1.5.3 full release. Mods please feel free to move this to correct forum, apologies gentlemen. Virtual Aerobatics public server v1.5.3u2a-20160328-211646.zip dcs.zip
