SLI GPU usage off by 50%

post #1 of 12
Thread Starter 
Just 10 minutes ago I loaded up BF3 and saw that the GPU usages were very different from playing last time, which was 40 minutes ago.

Without vsync it was supposed to do >85% usage on each GPU, here is what it looks like now

700

The top GPU does 100 and the bottom only 50%, the bottom is somehow messing up. IS THE CARD DYING NOOOOO!!!!!!!!!!

I tried in other games, same thing with vsync off, the bottom never goes above 55%! Now games have lower performance due to this. I had good 60 fps in bf3, now it is 45-55.


YES SLI IS ENABLED and the sli bridge is on.

NO, same settings EVERYTHING as when I had normal usage and fps.

Nothing has changed, I changed nothing. except for updating drivers, maybe I will rollback see if that improves.


EDIT: Fixed, sorry for not doing it before posting, I restarted comp, and took out sli bridge, put it back, now game has proper usage and fps.
It's all good, thumb.gif

Had this happe earlier today. Went from fine to second gpu 50% use, to second gpu 0% use. Wipe all the drivers out and reinstall, worked for me. Be sure to use a sweeper to completely wipe em off though. Hope this helps
