Digital Foundry decided to test the viability of 8K gaming with a GTX 1080 Ti SLI setup, and the lesson seems to be that more VRAM can't come soon enough. Obviously, gamers can get away with playing at or close to 8K with some thoughtful tweaking of the settings (Battlefield 1 supposedly works great at 7K), but the current hardware lineup merely gives us a compromising taste of what's to come.
