So does Metal 4 / GPT 3 allow you to emulate DLSS via MetalFX to do image reconstruction and frame gen?
Performance still doesn't look great - on an M4 Pro at 1080p in DLSS balanced (i.e. 540p internal render?) and with frame gen we're still seeing ~45 fps in challenging scenes. I've got a bad feeling what this will mean for input lag with those kind of final frame rates...
GPTK 3 supports DLSS "emulation" in Windows games that support DLSS. It's not enabled by default, you have to flip on an environment variable to enable it, and I also think you have to drop a couple of NVIDIA DLL files in a specific place? (Just saw a brief overview in a video on the subject, haven't actually seen it in action yet.)
