I used to lock the color profile of my LCD by powerstrip on my HD3650 and HD7750 GPUs, thanks to "Write directly to palette DAC" and "enforcecolor=1" settings in powerstrip, the color curve (LUT) from my icc profile freed from any rewriting events including all 3D games.
While the entech team stopped upgrating the powerstrip in 2012, My perfect solution stopped working with My r9 290 GPU.
I've tried CP keeper, color clutch, MCW, etc. not very helpful.
So is there any way to lock custom color curve with recent gpus(gcn 2.0 3.0 4.0)in ALL 3D games like powerstrip used to do ?
Not that I am aware of. The software probably needs to be updated to work.
