I've asked this in the VSR thread, but it doesn't seem to be the right place to ask, so I'm copying what I posted there, in here, because this is a massive letdown since I moved from Nvidia to AMD because I liked my previous AMD experience, but this has truly left a sour aftertaste:
I had an Nvidia GTX 970 before, where I ran 2880 x 1620 on DSR @144Hz with no problems. I used to love my 280X I had when I used it on my 60Hz monitor.
Yesterday I got an MSI 290X Lightning, and I cannot run any VSR resolutions on 144Hz - All are 120Hz and lower, most are 60Hz actually.
Considering the 970 and 290X are pretty equally matched in terms of processing power, I am really disappointed in this realisation. I thought going back to AMD would be a forward step, but now I am really disappointed. I don't like the way jaggies are processed with AA, I loved the natural way they look with DSR(VSR).
I sincerely hope this can be added sometime soon.
