You might be able to run it at high settings while maintaining around 30 frames per second.
Your 7770 requires less VRAM compared to your 580 even when running identical configurations, which makes it hard to be sure about those measurements. The big differences in GPU and memory usage aren't really helping the comparison.
Hey there, I’m using a GTX 580 and just played Fallout 4 for five hours. At high settings it works fine but feels a bit too many frames for smooth gameplay. Switching to medium helped, and lowering it to low still gives great results. Overall, it’s not the top choice for ultra quality in Fallout 4—especially if you’re aiming for that. Edit: I’m currently using 2560x1440 resolution.
Lowest requirements are 2GB to 1.5GB, though performance may drop slightly; at 1050p it should function fine.
