He did not reply to my PMs or questions in the threads.
I just know it looks fantastic (and yes, you can clearly see AA differences even @ 2560x1600 on a 30" screen).
The SLI modes that nHancer 2.4.1 recognises on G8x hardware running Fw 177.73 are as follows (you can still use enhance the app/Gamma correct/MS/SS transperancy AA on top of all these):
SLI 8x 4xMSAA + 2x SLI SS
SLI 16x 8xCSAA + 2x SLI SS
SLI 32xQ 16xQ CSAA + 2x SLI SS
SLI 64xS 16xS SSAA + 2x SLI SS (OpenGL only)
Mmm, i'm a bit confused. Is this SLI 8x mode using 2x2 SS + 4x MS ? Cause, this is called 16xS in single card mode.
I thought that SLI 8x was 4x MS (gpu1) + 4x MS (gpu2) + blend of the resulting images = 8x MS
Somebody should bring some light here
The main advantage of the SLI AA modes, is the lack of micro stuttering. You do not raise your frame rate, but you raise the AA quality.
