Let's say you're trying to play Alan Wake 2 at 1440p Ultra settings with raytracing and your older RTX card is floating somewhere between 30 and 45 fps. You can set the internal resolution to 1080p and let DLSS upscale to 1440p for you. Theoretically you won't see any quality reduction but the game will run a lot closer to 60 fps since the lower internal resolution is easier on your PC and the upscaler core on DLSS compatible video cards takes care of the upscaling.
There's a few things that could be coming into play for you:
- You just happen to have better eyes than most and can pixel peep the differences.
- You're using the wrong mix of DLSS mode and video quality settings in the game for your computer (DLSS Performance, Balanced and Quality all do different things so you might need to play with those)
- You're not matching your monitor's native resolution and a multiple of the refresh rate which probably means it looks bad regardless of what you're doing in the settings.
All I know about frame generation is from watching videos online, but they all seemed fairly conclusive that it's a powerful tool. It can introduce significant lag on underpowered hardware depending on your settings, and I believe I saw a digital foundry video where they showed raytracing getting a shimmering effect in Cyberpunk RT Overdrive mode. Sounds like Nvidia is dealing with that via ray reconstruction in a future update.
