As stated before, this is a software that will run smoothly no matter your hardware. The numbers speak for themselves. While testing the 5070, there were already times that the GPU was not running at 100% usage, and the fact that the 5070ti and 5080 performance results are so close shows that the software is running near its limits with higher end hardware.
The one downside we discovered in this software is that some screen tearing is basically unavoidable. Because there are no graphics settings, and therefore no option to enable VSync, framerates that exceed the output framerate of your display will cause some screen tearing.
That being said, it was not typically noticeable on our projector display, but your experience may vary.
Our recommendation for this software is to use it at 4k when possible, since even the most affordable computer hardware we offer will be able to run it smoothly at that resolution.
