I'm sort of the opposite. Higher resolutions are nice, but while the game isn't running fluidly it just sort of adds this malaise to everything. It does so in a subtle, insidious kind of way. You can play with a rough framerate, especially if you are used to doing so, but it just constantly detracts from the game and it can also screw you up in the game only leading to even more frustration. Would you read a book without glasses? Listen to music with a jackhammer going outside? I myself have run things higher in the past and taken a framerate hit, but it just ruins everything. You'd have more fun playing at a lower resolution with a solid framerate, but then you do have that lack of a higher res gnawing at you in the back of your mind.
I think in the battle between detail and framerate, you should always pick framerate. And this will force developers to adhere to keep optimization of things, not just the engines, in their mind if they also want to present high detail, less they get slammed on the performance of their game.
I've long felt that the PC needs to gets its stuff together in terms of controlling variance and setting standards or guidelines. Choice is fine but there's good choice and hard choice, and too much of the latter isn't all that fun. I'm actually kind of hopeful for VR. That will probably immediately become the high end and hopefully alleviate some high end pressure on contemporary display gaming, and then hopefully you won't have to pick between res or framerate like you do now sometimes.
I was thinking about 1440p recently. But I don't think I'll bother. I'll probably look at 4K after it's had time to even out a bit.
