Ahoy everyone, I've been unimpressed with my triple-monitor performance lately. I'm running two AMD Radeon Sapphire Vapor-X 7950s. Obviously these things are pretty beastly, and I've got plenty of RAM (16GB) and an i5 3570K to boot.

The problem is, even this rig can't run ultra graphics across 3 monitors. I really hope no one says "Well yeah, you just can't run ultra graphics on 3 monitors, period." because I made this rig specifically for that purpose. At the time I bought these graphics cards they were the 3rd or 4th most powerful on the market, so if not even two of them can do the job...

If I run a benchmarking software on ultra (I use Unigine) with crossfire on on just 1 monitor (1920x1080), the two cards perform beautifully: I rarely drop beneath 30 FPS and occasionally hit over 100. However, as soon as I set my triple screen display up (5760x1080), disaster strikes. With crossfire on, I can barely manage 15 fps with major screen tear and stutter. I heard that turning crossfire off actually helps on multiple displays: it doesn't. With crossfire off I barely hit double-digit fps. Here's a link to some screenshots so you can see what I mean.

So I guess it all comes down to this: did I waste my money, or what? Am I doing something wrong? All I want to do is play skyrim on ultra on 3 monitors please tell me how to make that happen.

this is normal. crossfire + eyefinity is a known problem. 2 cards performs equal to or worse than one card with 3 monitors.

so yes, you did waste your money, crossfire is poo. sell your cards and get a better single card like a r9 290.

Ugh, the specific reason I chose to buy 2 AMD cards instead of 2 Nvidia cards is because I was assured that AMD was better for multi-monitor gaming because of the larger graphics bandwidth/memory...

Will a single card run skyrim in HD across 3 monitors at 60fps? I doubt it, unless it's a Titan or something...

you could wait, and see what happens, as apparently amd are working on a driver solution to this problem. If it were me, i would not hold my breath for it, just sell the cards for whatever you can get for them, and aim for an r9 290, which should be capable of running triple monitor skyrim with no problem.

Honestly I'm just done with AMD. Way too many problems. I should have just gone green team from the beginning. Guess it's time to buy some 4GB 770s...

Oh and just for fun I just upgraded my drivers to 13.8, the ones that are supposed to "fix" eyefinity (http://www.tomshardware.com/news/AMD-Catalyst-13.8-beta...). It didn't. I got the exact same benchmark score and it still looked awful.


Feature Highlights of the AMD Catalyst 13.8 Beta Driver for Windows:

Support for AMD CrossFire Frame Pacing
Frame Pacing ensures that frames rendered across multiple GPUs in a CrossFire configuration will be displayed at an even and regular pace.
Enabled through the AMD Catalyst Control Center; globally or on a per application basis.
Frame Pacing is enabled by default.
Supported for DirectX 10 and DirectX 11 applications, and resolutions up to and including 2560x1600 (single display).
you will be happy with 2 770's, from what i have seen work flawlessly triple display. but still, faster single card is better. I have had both crossfire and sli setups on a single display, and an equivalent single card still feels smoother.
