fixed the issue with destiny, head into NVIDIA control panel and under "adjust video colour settings" select "with the NVIDIA settings and drop the saturation bar down, its this setting that bleaches out the screen, no doubt it should work with other games have have issues too try it and see
That's a strange one, wouldn't think the video colour setting would alter anything other than like video files or something, I mainly game on my Acer X34P now so no HDR but if I do get another HDR screen I'll definitely give it a go!
