@Neinx Try using this Aspect ratio it looks way better than that and increases performance by quiet a lot:

1152x864

Been using that for a bit and it increases fps by a lot. at my native res i can only do all normal settings and i get like 20-25 fps with a bit of stutters but with that res i can enable some stuff on high even textures and it plays at 30fps its pretty damn weird but it works so try it out man can't say for sure it'll increase your fps by a lot by my specs are
550 ti 1gb
fx 6300 (stock)
and 8gb ram

@420x420 i have laptop and i cant aspect ratio when i try it i have blackbars

@Neinx are you doing it from ingame? what is your native res?

@420x420 1366x768 is my native res

@Neinx gta 5 shouldn't do black bars it should fill yourscreen did you even try the 1152x864 res?

Once installed is it possible to turn graphic settings up in-game? Because I do photography and want good quality pictures but less lag while doing my cars etc up.
