I've tested Half Life Alyx, Moss and No Mans Sky today on Ultra 90hz and got crazy high reprojection rates and still dropping frames just not as bad as before. Alyx was OK and somewhat playable if you could look past anything moving ghosting like crazy. Moss was somewhat playable but also ghosting; getting like 35-40 FPS. No Mans Sky was completely unplayable. Other titles that I've played for years aren't working either, titles with zero demand for any modern GPU, one called Tower Tag; it's completely unplayable as well.
This is with a fresh install of Windows 10, completely up to date. All RGB controller type software off. I even updated the firmware on the card from Gigabyte's website and still no improvement. I also lowered the power-limit to 80% just to see if that perhaps made a difference. Nothing. I even tried changing XMP profiles and disabling XMP profiles, nothing. Something is definitely NOT ok.
I'm considering trying to return my card already...this is getting friggin' stupid. Insane hardware costs from HTC, insane hardware costs from NVIDIA and we're months into the 4090 launch and no fix....heck, no WORD from anyone.
System is:
ASUS x570 Tuf Gaming Plus wifi
Ryzen 9 5950x

Gigabyte 4090 Windforce
