Emu crash when i use Buffered rendering

[Stevec]

I started setting to 1xPSP was fine - just looked blocky and dark - no crash, then went 2xPSP - looked better no crash - then went 3xPSP - f1 gp worked ok - but on same settings hot wheels would crash - so not sure why but the auto setting (1:1) was too much for my system. (I played for over half an hour on a couple of games no crashes - rechecked games that were crashing even with fxaa on the whole time and all running at 60fps 100% - changed back to auto 1:1 crash within 10mins or sooner -very weird!) Games look really smooth now! with fxaa on
