I have an RTX 2070 Super in my workstation, but my son has a GTX 1660 Ti in his gaming rig. I've run Cycles on the latest builds in both machines. Obviously, with the GTX 1660, I can't take advantage of the Optix RT features, but the Cuda drivers still work well. The speed difference in certain scenes can be substantial (Optix vs. Cuda), mostly due to the fact that I can get sufficient samples about twice as fast on the RTX card to engage the Optix denoising. On the GTX, it takes a bit longer to get sufficient samples to use the denoiser, and I usually use the Intel OpenImageDenoiser node instead of the Optix AI. I think The Intel node is great for denoising, but it definitely takes longer to get the samples on the Cuda driver than the RT/Optix.

Yes, I noticed this, but since I don't do final renders in Blender (unless working on one of your fabulous tutorials ), I'm not too worried about this. That could change at some point with Blender 3 and Cycles X, but I'm not worrying about it now.
