Now lets step things up a notch and check out how a single GTX 780 performs with ultra textures at 2560×1440 resolution. For this test, we used the same advanced settings as the 1080p run through:
Usually when going from 1080p to 1440p, you expect to lose anywhere between 20 and 30 frames per second on average. Here's our benchmark result:
Going from 1080p to 1440p with the same graphical settings cost us 20 frames per second overall. However, we still managed to maintain a smooth frame rate, coming in at just under the 60 frames per second sweet spot.
Once again, you can see the minimum frame glitch. I can confirm that this frame drop occurred as the benchmark was loading and not while it was running. Additionally, while playing the game I didn't notice any severe frame drops, slow down or stutter, so its not much of an issue, the frame rate is generally solid.
At 1440p with ultra textures, we observed the game using up to 3032MB of VRAM, there is still a tiny amount of headroom left as the GTX 780 has 3072MB but it looks like gamers will be better off with a 4GB GPU.
