AMD RadeonSI Gallium3D Performance For 4K Linux Gaming

[liam]

I just bought a new 40" 4K TV (Samsung UN40HU7000, $950).

I'm running a 7970 with the latest Catalyst drivers from rpmfusion for Fedora 19.

Forget gaming, I just want the desktop to work.

Firefox *really* doesn't like windows larger than about half the screen, before everything almost comes to a halt (scrolling, typing in text boxes, etc).

I can get a 1080p video to play full-screen, but I tried the 4K Elysium trailer and only Totem could even put something on the screen, and that glitched and the sound dropped out. At least that was better than gnome-mplayer, VLC, and Youtube+Flash, which I didn't get anything from.

How are the oss drivers?

Always interested in 4k numbers. Do you have on the agenda a 4k vid test?

Yeah... that being said, I'm not upgrading from 1080 for a long time. I personally think there are too many downsides to UHD - the overall performance loss, so much wasted horizontal space on web pages, any software not optimized for it looks tiny, AFAIK there are no movies or shows higher than 1080p, and I also just have no use for that much screen real estate.



So Michael.... when are you going to get a KVM switch? Seems like your setup is getting pretty out of hand. You could save a lot of space if you ditch all those monitors and keyboards.

personally, I have one.you just have to rethink the way you work. Split screen everything.

Very nice.

I'd love to see you get a DP monitor so you can test a bit older cards.

AMD specs for 6870 say the max res is 2560x1600.

I do have a KVM switch but never use it.... My setup works. Sometimes I end up using 4+ keyboards, monitors, and mouse simultaneously.... One computer for my emails / article writing / Internet surfing / business tasks. Then anywhere from 1~3 systems concurrently running benchmarks. Then usually a separate system when I'm working on / testing PTS/Phoromatic/OB code. I prefer having dedicated monitors so I can see when a test is done (albeit PTS can also email / txt me) but especially for making sure the system doesn't hang or that when running any graphics tests there are no artifacts or anything, so will be monitoring them with my peripheral vision.

You could rotate the monitor and use it in portrait mode.

I only have UHD, but you definitely still need antialiasing. The problem is since the screen is so large, the PPI is nowhere near what a smartphone has. You really need at least around 200 PPI from a monitor before jaggies start disappearing without AA.

I can't imagine me using 4K for anything in the near future, but an interesting read non-the-less.

Presumably you wouldn't need to use any AA at this resolution?
