When CUDA acceleration is active and I want to export a DDS using the latest nVidia Texture Tools I get a corrupted image when I display the compressed version like the screenshot. It will also save a corrupted file.
If I change the compression quality it will most of the time move from CUDA to CPU (not sure why) but after the switch the display compressed functions like it should and doesn’t show a corrupted image anymore.
I tried several drivers (now using latest Creative Studio Driver), got rid of other DDS related plugins but it doesn’t help.
Since I use a massive amount of software using CUDA acceleration without problems (KeyShot/PhotoShop/V-Ray/Resolve/Substance Painter etc etc) I reckon the bug is within the export plugin.
A reason could be it doesn’t like the fact I’ve two 1070’s in my system (SLI Disabled). Anyway, doesn’t really work like it’s supposed to do. Another minor thing, if it switched (for whatever reason, 4K textures) to CPU the ‘display compressed’ option is terribly slow. Closing the window and opening it again makes it behave at normal speed using CPU (i9-9900K).
So actually two bugs I think. I was wondering if there was some beta to try since it really slows me down while creating a load of DDS files. The older (guess not CUDA accelerated) plugin does work but misses some of the options I need.
Hope you guys/girls can help me out or give me some things I can try to solve it.!
After typing this I was thinking what would happen if I forced CUDA on one specific GPU using the control panel. Well If I selected the second card it wouldn’t even do GPU acceleration. If I selected the first card it works without corruption so far. So definitely a bug in the Texture Tools Plugin I would say.
