    Why has nobody told me about this before.

    I'm such a noob at computers in general.

    I enabled it in the driver, along with gpu scaling and set the resolution to 2550 X 1440. My TV is a standard 1080p panel.

    So obviously the TV can't display more than its highest resolution right?

    Am I seeing an image that is basically got huge anti aliasing?

    Either way it looks amazing compared to what I had before so it's a win!

    We do the same in our vr headsets for sharper images

    Pretty much. What happens is, your gpu renders the game at twice the resolution and then downscales it to 1080p which, in return, gives you a sharper image. SSAA is pretty much the same thing so if you have VSR enabled, do not enable SSAA in games (if they have this setting of course) because it will mean you'll run the game at an even higher resolution and the performance will be much lower :)

    What surprised me was the fact there was no noticeable hit on the frame rate.

    I was expecting it to be much worse but I'm not sure it's made any difference.
    If anything I'd swear it was actually better.

    Nah, it will affect performance the same as if you play on 1440p standard resolution as opposed to 1080p. Basically the GPU has to render everything in higher res, and then downscales it back to 1080p, so the penalty in FPS is at least as big as playing in a higher resolution.

    What GPU are you using ? Maybe you could go even higher res for even better aliasing ! If you didnt notice a big FPS hit at 2550 x 1440 .

    An RX480

    There are a few higher resolutions available, so I'll give them a test.

    My previous GPU was a GTX 1060, that could do 4k pretty well, could get 60fps with high settings.
    From all the benchmarks I've seen it and the RX 480 seem pretty similar so you might get lucky.

    How would this work on 3x22" screens? I am currently running at 5760x1080. Would this help or hurt me? I am running an FX8320 and R9 290. I am afraid to test as my current setup works really well. I typically get 60-120 frames depending on track and Mod.

    If it's not broken, don't fix it.

    It would work - it's the same as DSR on Nvidia cards.
    The issue being the performance impact on your GPU would be 3x higher, as you're rendering to 3 displays. So logic would suggest that the resolution you could render at across 3 screens with a given GPU configuration would be lower than the resolution you could render at with a single display.
    There's no harm in trying it out, but likely you won't be able to increase the resolution high enough to see a noticeable increase in image quality.
    If I were you I'd likely stick with applying various forms of AA. And you should experiment with AA through the graphics drivers, vs AA via the game itself, as you can noticeable performance benefits using particular types of AA with certain GPU and software combinations.

    ...so I tend towards Comante's comment - "if it aint broke - don't fix it".
