The problem here is that VKD3D-Proton runs very poorly on GTX 1000 series cards so if you do get it running don’t expect amazing performance. I was getting only 20 to 30fps on my GTX 1060 when on Windows I would have gotten a stable 60fps.
Post your GPU driver version.
That’s the issue. You need the proprietary driver for Elden Ring to run on GTX 1000 series.
