DLSS only works with the nvidia Studio driver.
DLSS doesn't work at all, literally 0 affect on FPS with the Game Ready driver installed. Works perfectly fine with the Studio driver.

I didn't test with Studio Driver, but indeed with 496.49 driver, with a 3090 & i9-10900K, DLSS isn't giving me any boost at any DLSS settings, while I can see the quality going down, so DLSS is working while not increasing the FPS.
2560x1440p with G-Sync, full screen, Ultra settings, V-sync off in-game, and on in nVIDIA CP.
With RT AO I'm at ~90 FPS, with or without DLSS. GPU usage at 74 %.
Without RT AO I'm at ~130 FPS, with or without DLSS. GPU usage at 96%.
If I put DLSS on ultra-performance, it even gives me less FPS, like -3 FPS.
