Yes, frame gen would be much appreciated.
Alternatively, the option to adjust the neural rendering resolution from 100% to a lower value would be useful. Apparently, you can do this if NR runs through OptiScaler, which I was curious to know if this add-on uses, given the lack of ReShade.
I think you need to be careful. Reports have come out suggesting that cards running the leaked DLSS5 have been allowing their hotspot temperatures to go up to 104°C.
I'd recommend undervolting and power limiting your card and see if it makes any difference.
