I'm using the DirectML fork of A1111 because it's the only one I can get to work.
For professional reasons, I have to have an AMD gpu. I had a 6650 and was able to upgrade to the 6700xt for the extra vram, but the change has made no difference in errors telling me I'm out of vram.
I am a fairly frustrated because it seems I'm locked out of a lot of really neat and powerful features. Generating a batch of 4 images at 512x512 already takes a couple minutes. Moving that resolution at all jumps up the time considerably. I can do very little with img2img and ControlNet is effectively useless for me.
So, now that I'm done whining, is there any news about AMD improvements that might bring performance up to even a decent level with comparable Nvidia cards?
A direct hop is usually not the best way to move into the Linux world. The best way I've heard (and wished I did myself) is slowly start migrating to programs that will be available and you'll be using, while still on Windows. Get used to how new things work and if an emergency comes up, you can fall back to your tried and true tools. Then, just keep migrating apps until most of what you use is open source stuff, or stuff widely available. (Spotify, Discord, Zoom, etc.) Once you have your workflow worked out, you've found substitutes for things you can't get on Linux, then is a good time to take the plunge.
Going cold turkey is going to be really rough. I had Fedora on a side piece laptop for years before my first try on my workstation and it was a disaster. Less than a week later I had to go back to Windows. But, now I'm familiar with the tools I use and I've been a full convert for a few months now and it's been great.
You can do it! Just...take it slow.
