Tested: the DLSS 3/FSR 3 mod that brings frame generation to older Nvidia cards

Frame-gen for older RTX graphics cards? Digital Foundry checks out a remarkable mod.

Looking at the Cyberpunk 2077 benchmark using RT Overdrive at 1440p DLSS performance mode with ray reconstruction active delivers a circa 67 percent uplift in frame-rate, so we're moving from the 50s and low 60s to something in the region of 100fps, a good match for a high refresh rate VRR-capable display. Basically, traversing the denser areas of terrain more rapidly or engaging in combat could see erratic frame-times, so even though FSR3 was supporting variable refresh rate monitors correctly, it still did not look smooth in such moments. Another issue is silhouette and hair artefacting (as seen in Alan Wake 2) where moving the camera from left to right delivers a kind of fizzling and haloing around the character's head with the FSR 3 mod.
