> To me, the argument against a proprietary driver seems extremely weak if you're running Windows anyway, but I guess they see it more that if more game devs can run the RADV driver, they can get wider testing (or a simpler story for devs to test at least) and backdoor improvements into the Linux side?

Are you using an AMD driver?

Let me share my experience. One day, you wake up and your GPU driver is gone for no reason. I'm not even joking here—the recent driver update broke the driver for many users. Launch Battlefield 6, and your driver is... gone. A new driver update comes out... Launch Battlefield 6, hard freeze. Improvement. I'm still running an older "blessed" driver version for this reason, and I'm scared to update.
