GTX 970 Performance at 768p

[amadeok]

Hello,
I have heard that playing at 768p will decrease performance because of the load shifting to the CPU or something of that sort, thus decreasing performance. Would you know anything about this?
Anyways i can always just use DSR to dowscale 1080p to 768p, but i went for 768p mainly because of the better FPS and the lower VRAM consumption, not really for today games, even though many games are already going heavy on the VRAM also at 1080p(www.tweaktown.com),
but for tomorrow games, one or two years from now, considering also the 3.5GB + 0.5GB issue on the 970, and that i use decent amounts of AA, imo low AA is immersion breaking.
Nevertheless i have seen a benchmark where 768p was getting+20 FPS from 1080p, thats promising in my opinion. The DPI isnt that much greater in 1080p, doing some maths(http://dpi.lv/) we are speaking of 86 DPI for a 18.5 panel at 768p and 102 DPI for a 21.5 panel at 1080p, thats 18% more.
Please share your thoughts

I told you, the 970 can easily handle 768p.
I have tried all three of 1024x768, 1440x900 and 1920x1080, and 1024x768 looks nowhere near 1440x900, let alone 1920x1080. Also, you don't necessarily have to max everything out for it to look good. A good balance is pretty easily achieved, trimming out the extra hifi stuff (such as 8xMSAA, 'cause 4x or even 2x AA works fine at 1080p) can up performance significantly.

Yes i know thanks but how can i get more detail in a 768p nonitor?

^ you can't !
Your best DSR resolution is going to be 1440p - this is going to look better than 768p even with aa enabled but its still a fake resolution - you don't get any more detail but it will smooth any edges better then aa will do.

It'll also push your 970 4x as hard as 768p & nearly twice as hard as 1080p though.

Which is why we all said you would have been far better off with a 1080p screen.

I understand thanks you. The pixel stretching, i dont know how to call this problem, its like the pixels are not enough to form a straight image, is noticeble mostly in foliage and thin objects like rops ect. Will DSR help with this problem? Cities XL surely improved. Also would you know how to make the windows font look better? I'm on windows 8.1
If DSR fixes this problem i guess i cant really complain. I would have most likely used DSR even if i had got a 1080p screen. Probably i would have use 1440p to 1080p or 4K to 1080p.

I'm opting out of this thread.
I'm done explaining.

By way of parting words, I'll say this: You want to use DSR to convert 4K to 1080p or 1440p to 768p, and then fret here about having performance bottlenecks and being paranoid.
Just get a good quality 1080p screen with bright colors and a good PPI, set your games to 1080p and enjoy the visuals.
Otherwise just accept that yours is a 768p screen. Just using DSR will not magically convert your 768p screen to 1440p.
That's it, bye.
