#Optimizations for eGPU setups

I'm not much of a technical person when it comes to these things, But I do know that setups where there is an eGPU are limited in terms of bandwidth compared to a regular PC due to its direct access to the PCI lanes and whatnot. I do observe that certain games (Mostly older titles, but no so old) are not that much affected by this limitation in my experience, games like Alan Wake, Control, Monster Hunter World, even Pirate Yakuza to some extent as well do seem to perform quite well in my setup, And as for the racing games that I own (GRID 1+ 2, Burnout Paradise, Need for Speed Hot Pursuit) they all perform well at max settings 60fps+ For this game I noticed that I can hit 60 at native resolutions (1080p or 2560x1080) but ill have to set the upscalers to performance-balanced often times resulting in a blurry image in the distance which makes it difficult for me to see the things specially at high speeds. I also noticed that setting both the Detail Quality and Environment Quality to medium or less allows me about 10fps more, everything else has minimal impact performance wise if I set it to High. I also used the auto detection settings and while it put everything on High, I could not sustain a stable frame, it would dabble from 48-67 or so. So i worked around this by capping my frame to 30 in game (which did not work, actually in my experience none of them worked) and i followed up by capping it to 30 at a driver level. That helped the game stay at a constant 30 which did help the experience. Here's a video basically showcasing on the top left that the game uses the GPU a lot more than the CPU, sometimes 30-40% more. Again I'm not much of a technical user in these matters but in case this calls for some balancing/optimization on how the workload can be more distributed, having these setups in mind, I placed this here along with my full specs.

I also run this game via Wine on my Linux PC but I highly doubt the performance in this case has something to do with that.
