I finally got decent parformance out of FM. I followed this guide...
He does a good job describing what the graphic settings do. This made a big difference for me. Its pretty damn smooth now.
Edit...
I have had C: drive issues for a while. I only had a 128GB SATA SSD as my C: Drive. I recently bought a 2TB M.2 NVME and finally got the SATA SSD cloned to the NVME. Before cloning the drive, my paltry SSD was full, and I wasn't able to update my Nvidia graphics drivers. With the new M.2 I was able to update it.
Why is this relevant? NVidia took it upon itself to change my graphics settings in order to "optimize" Forza Motorsport. I now want to find Jensen and cut the sleeves off of all his leather jackets! I didn't play it yet, but I am about to see what Nvidia's idea of optimized is. I have a sneaking suspicion that it ain't going to be good though. They turned the resolution scale to 80%, Put the windshield reflection on Ultra, set the track texture quality to Auto and turned Ray tracing back on. This is going to be a hot mess.
