4k resolution coming

4k monitor is great, but while I'd like to buy one right now, I know I can't play any games with that resolution yet. Maybe some older ones... but 4k resolution hack with muddy textures don't sound fun. Many older games crash or don't work correctly with wide screen full HD already.
For those who have multi titan setups, they can enjoy this right now. Rest of us have to wait graphics card gen or two.

I mean that's it's unlikely that texture resolution will be 4096x2048 or 4096x4096 for full field of vision (meaning roughly getting as close as you can head on towards wall or other obstacle) in next gen consoles and thus in PC games. This means muddy textures (obviously much less muddy then now, but still not pixel perfect).
For old games... well, I guess I could play some last gen game with 256x256 or 512x512 textures and with 4k resolution, but it ain't enjoyable at fullHD resolution, so I doubt anything would change much. Yeah, there would be even less jaggies then now but usually you can max anti-aliasing anyway.
But when we do get to the point where 4096x4096 textures are common (or similar quality megatexture or other technique), 4k resolution will be great. Maybe it'll happen in next gen. I asked about this in some other thread in this board, but I dont think anyone knew if it's possible or not or how developers choose to use their 5-7 Gb memory.

Actually, no. You don't get "pixel perfect" anything from a 3D game, as most textures are resized during rendering. For example, a wall with a 1024x1024 texture is good enough when it occupies only 1/4 of a 4K resolution screen. Similarly, a billboard with a 512x512 texture is good enough when it's only 1/8.
In 3D games, you can never have "big enough" textures because the camera could be very close to an object. (e.g. a wall can be 10 times the resolution of the entire screen) Since it's generally impractical to make a texture large enough for the closest possible distance (e.g. in most games you can be very close to a wall), you get "muddy" texture no matter what. On the other hand, if you use some tricks to make textures less "muddy" (the prevalence of pixel shaders makes many of these tricks possible now, in real time), a screen with 2x resolution is not going to make it "muddier" than now.
Old games (circa 2000) are fine at 4k and fullhd (i'm guessing you mean 1920x1080)
If your talking old console games from that era, how would you know , as youve never played an old console game at fullhd, what you have done is play a standard res game that has been upscaled to fullhd which is not the same.
Why they are common texture resolutions for current games, on Rage the pc version you can tell the game to use 16,384 x 16,384 size textures (the default is 4,096 x 4,096)

Yes, I have a feeling that you are right and we'll not reach that texture resolution. But I guess that's not generally a problem, since I don't think I've ever met another player who's main problem and sometimes even reason not to play are texture resolution. Just about everyone are more interested of various anti-aliasing methoids, polygon count, shadow / lighting quality or various shader effects.
I still hope that collision detection keeps us somewhat far away from walls and we'll make it close to pixel perfect texture resolution. Maybe death animation and collapsing to floor is unavoidable barrier
Davros, if I understood correctly, PC version of Rage uses megatextures and while texture size is large, it also cover a huge area, thus make it look even muddier (sorry to use this unofficial term) when looking it at close range. Not that other games do much better with traditional tech.
For example pic from Metro 2033
Shows what I mean. It basically cover my whole field of view and is extemely blurry and low resolution texture. Thus that wouldn't look any better in 4k.
Apologies for thread derail.
No, look at the text, it's clearly pixelated and unreadable.
It's clearly upscaled, is what they're saying. That's not deliberate texture smudging to simulate the look of the map in real life. The text is deliberately unreadable, but the fidelity is less than 1 texel per pixel. The solid lines show clear pixelation - they should be pixel perfect.
Exactly, except I'm not sure the text is deliberately unreadable in the "clean" parts of the map. There's really no reason why it should be.
Edit: the difference in sharpness between the map and the picture frame suggests that the map is just a relatively low-resolution texture, and ArcticCircle is right.

A 2k texture map is too low for perfect 4k video. If the map is 1k, it's even worse, and looking at the screenshot, I wouldn't be surprised if it was a 512 texel texture given degree of upscaling.
Technically, if you want to avoid aliasing, you should have less than 1 texel per pixel.
Surely antialiasing would be handled in the texture like any 2D image? Lower texel densities are the same as upscaling a 2D image, meaning less aliasing and more blur, unless I'm completely misunderstanding you.
I'd love to have that explanation some time. Make a topic some day! Write an article! Blog it! Tweet in 238 parts!I suspect I'd need a whiteboard to explain and, perhaps, a lot more time than I have at present.
I think simon means High Frequency Aliasing
