I can only speak of the UT4 Pre-Alpha builds and the UE4 Demo’s. I have an AMD GPU with its Scaling options set to either ‘Maintain aspect ratio’ or ‘Use centered timings’, but when I set the ingame resolution to 4:3 or 16:10 via the ini configs or ‘r.SetRes’ command then the UE4 engine simply stretches the resolution to fill the entire screen.
Is there another command I’m missing or is this broken? The only way I can force the correct aspect ratio is to change the desktop resolution before hand, which is annoying as I have to keep changing it back after I’ve finished playing/testing.
I have the AMD HD7870 with latest drivers on Win7 64bit.
