Is there anything special about VSR? Isn't it just using the display controller's scaler to downscale a larger framebuffer to the display pixel size? I think this has worked for a number of years already, although it is not set up automatically with X drivers.

I was going to ask the same thing. I tried it recently in Alien Isolation because the aliasing is hideous. I ran into an issue with SDL 2 but I was able to get it to work. I've offered to fix it properly but haven't had a response yet.

Also is there some git repository we can grab this from? I can't find any updated ones on cgit.freedesktop.org.
