I was wondering what these do and their performance impact. I have been having problems with fps lately and wanted to know what 2.00x (native resolution) and 33% smoothness do to the quality of games and performance. Thanks

I use DSR quite frequently so hopefully I can help. So if your using a 1080P monitor and using 2K DSR the system will render the game at 2K (2560x1440P) then it scales back to your native res and by doing so makes the game look a bit better however because the system is running the game at 2K it's a much heavier utilization on the system then at 1080P so your FPS will be lower.

For example my native monitor is 1080P but in some games I use DSR at 4K so the game normally will run at 150 FPS at 1080P but when rendered at 4K it dips down to 60 FPS since its rendering a higher resolution.

As far as the DSR smoothness (sharp vs blur) 33% is the default by Nvidia. I've tried higher and lower values but TBH it doesn't look as good as the...

Would it look noticeably worse if I decreased it from 2x to something lower like 1.5x?

In most games no, like I said there's really only a few games I've seen that made a really big difference. Depending on the game and your setup you might be better off staying at your native res and then make adjustments to AA to find the best performance/graphics to your liking.
