Hi Calamity,
I am done another test:
i am just installing clean configuration with dual monitors and have sound/video slowdown too....
indeed i am just installing an new Win7 X64 ultimate & GW:
Win7 x64 ultimate+I5+8GoDDR3 + Ati radeon 5450 (1Go)
+ CRT Emudriver & CRT Tools 2.0 beta 15 (Crimson 16.2.1 non-GCN* cards) for Windows 7/8/10 64-bits
I have again sound/video slow down like my old configuration:
Win7 x64 + Intel Core 2 Q9690 + 3GB +ATI Radeon 4800
+ CRT Emudriver & CRT Tools 2.0 beta 15 (Catalyst 12.6) for Windows 7/8/10 64-bits
So problem must by with GW since 0.237
Have you some test idea?
Best regards,
Bertrand
