I have even verified the environment variables are being set but vsync is still being enabled. Using the old driver I get 200-300 FPS after the first boot and with the newer ones I am stuck at 48 FPS:
Code:
root@sigoto: 03:27 PM :~# ps aux | grep X | grep -v grep | grep -v Box

root@sigoto: 03:28 PM :~# cat /proc/17218/environ | awk -F'_GL' '{print "__GL"$2}' | cut -c 1-21
__GL_SYNC_TO_VBLANK=0
Any other way to disable vertical sync other than environment variables? They don't appear to always work with everything.
