Would the Radeon RX 7900 XTX graphics card be a good one for smooth running of twinmotion?
Short Answer. NO.
I have one and I tried it and it did not perform. Crashed when I tried to export raytraced images. I did a test render with non-raytraced images between the 7900xtx and a 3060 and the 3060 beat it with 10 mins. I would also like to mention that the 7900xtx is a bit buggy when used on TM. Buggy being unpredictable when exporting images. You may or may not finishing exporting the images. So I ended up with an RTX 5070.
