Some more quick tests on GTX660Ti small overclock.
GSCE- Looks better at 2351x1323 with 2xAA, 25% DSR smoothing 150-200fps track map & fraps working as wombat.dll not needed.
Assetto Corsa-Too much of hit fps wise so will probably not run it at the moment and also the driving experience is not great anyway.
Battlefield 4- 1920x1080 AA deferred off, AA post High, 25 % DSR Smoothing gain about 30fps and looks better.
Wasteland 2 Resolution changes dont seem to be recognised, 25% DSR Smoothing small 5-10 fps hit, Looks a bit nicer.
Batman Origins- 2351x1323, FXAA, 25% DSR Smoothing doesnt hit FPS much and does look nicer.
So what can we conclude from this. Probably best way to describe the effect is some you win, some you lose.
And I have just lost another night of my life playing with graphic settings when I should be enjoying my gaming time.
Need to punish myself now.
Last one promise.
