Hi hello, currently Virtual Super Resolution only works on an arbitrary list of resolutions, but on resolutions such as 720x540, 800x600 or even 1024x768 (which is 4:3 1366x768) or even refresh rates that exceed or are inferior to 60hz, the option will be entirely abssent. This is also an issue for 21:9 and 32:9 panels, since the option is absent there too.
This is frustrating in comparison to how it works on Nvidia's drivers, which you can add virtual resolutions on a 2x, 1.5x basis to *any* resolution.
This has been an issue for years, ever since the option was introduced. Frankly, I'd prefer if AMD settled for a more than "good-enough" approach to its drivers.
