yes i noticed this unync sli stuff with alt-tab too. I think i will wait for a new nvidia driver, or a new p3d version to see if there is some changes for my setup... i should have keep my 2 780ti, p3d was running very fine... :(

thanks for the answer, but when i had my two 780ti in sli i did have fps improvments... With the same scene at the same place, i had much more fps with the 780ti's than the 980ti's I did some sli testing with 3dmark and others games, and the sli works fine... in sli mode the two cards are running at 25%, i feel like the cpu is bottlenecking somewhere... i checked with cpuz, when p3d is running, i have 4.6ghz... so no problem either...

Hi, I used to run p3d 2.5 with win 8.1 64 and two 780ti in sli. It was still the period of the AFR-FriendlyD3D trick. At this time, i had a nice improvment in sli configuration. I changed my cards for two 980ti, the new nvidia driver with p3d sli profile came out, and now my p3d has no improvment at all with sli on. The fps are exactly the same with or without sli activated. In msi afterbuner, i can see that the two cards are working but not a fps more... Weird thing isnt'it ? Is anybody has the same problem ? Thanks
