Hey, I play this soccer game, PES 2014, and ran almost perfect on PD8. I finally decided to upgrade to PD9 and the game runs even smoother, but I get this now : http://s10.postimg.org/yksar78pl/PES_2014.jpg Sometimes it flashes, other times player's shirt turn black for a second or two. So far, I've tried turning v-sync on and off, changing the resolution of both the game and Windows and played with the virtual machine's settings (switch from 4 cores to 3 and 2, lowered the ram from 9Gb to 4Gb). I haven't tried lowering the vram yet.. but I don't think it would help much. What do you think it is ? Like I mentioned above, I never saw this on PD8. Thanks a lot and happy new year to you all.
