Dsr works perfectly. Heres my take on it since I am extremely heavy into IQ over performance. While testing at my native resolution, 1920X1200, Absolutely no AA, compared to 4k with absolutely no AA, just speaking in general, There is a big difference in IQ, however, If you was going to compare the 4k with no AA to 1920X1200 resolution with nvidia inspector Absolutely insane AA settings: 32xS [Combined: 2x2 SS + 8x MS] + 8xSparse Grid AA???? Absolutely NOT!!. @ 1920X1200 resolution w/ 2XMSAA + 2XSparse Grid AA provides alot better IQ then 4K without NO AA. I also tried to see if I can get a similar IQ, AA speaking @ 1920X1200 to roughly match up with 4k without AA, Heres what I found out: 2x2 Supersampling AA provides roughly the same IQ as 4k(DSR) With NO AA. Another Thing I tried: @ 1920X1200 resolution with: 32xS [Combined: 2x2 SS + 8x MS] + 8xSparse Grid AA I tried to see If I can get better IQ @ 4k resolution without using the insane AA settings mentioned above as I am defint out of frame buffer at this point, So I tested 4k(DSR) w/8XMSAA + 8XSparse Grid AA, and the IQ is somewhat better then using 1920X1200 with: 32xS [Combined: 2x2 SS + 8x MS] + 8xSparse Grid AA But not by awhole lot, but if you know what to look for while a particular game is in motion, there is a quite a bit of difference, an average person playing the game probably wouldn't spot it at first, certain things needs to be focused on and can tell a difference right on the spot. I like it, thanks a bunch. Overall? I'll be using it from now on, good stuff? kinda, yes. If I had alot more video ram, I could do more but my gpu would cripple to its knees as I go very crazy with IQ within nvidia inspector, it would literally crush the 690 to its knees or any video card on the market today @ 4k res with the settings I use @ 1920X1200. Absolutely BRUTAL IQ settings, That's probably not even the word for it.
