Noice. I'm all for companies continuously improving their product.
I'm getting worried.
Any idea if my SLI'd 1GB Vram GTX 460's will be able to run Dead Rising 3 and The Evil Within?
Dead Rising 3 will run alright on medium, at sub 1080p. You'll get more performance if you leave the internal renderer at 720 or 900p. Even on higher end hardware, the game doesn't scale very well. Expect choppiness in cutscenes,. but general gameplay will be okay.
Of note, my 760 and 2500k achieve around 20-30fps at 2560x1440 with a mix of high presets. Had to scale shadows and ambient occlusion back a bit, they take a huge toll on performance.
For Evil Within, the community rep was a bit of a goose when it came to requirements and has demonstrated a lack of understanding when it comes to hardware, made evident from his interaction with forums. It'll run, don't worry about it, but don't get your hoped up with running all the sliders pushed to the right.
New consoles means we are getting higher res textures and those sum bitches take up a lot of VRAM. For a long time PC users have cursed out ports for lack of quality textures, but with 1440p becoming more popular with enthusiast and combine all the filtering on top of that, 4gb is going to become more and more common with videogames. 2gb will become the minimum, 6gb will be the new hotness.
