Nice write up and high resolution videos of game play. But of course, never as good as a GURU3D review http://www.pcper.com/reviews/Graphics-Cards/Frame-Rating-High-End-GPUs-Benchmarked-4K-Resolutions
As the review notes we're still a good ways away from gaming at 4k on a single GPU. There is also the fact that the only 4k monitor i've seen is the Sharp PN-K321 which is supposed to retail at 5,500$ lol. For 4000$ less i can get pretty close to the same pixel count in a multi-monitor setup. Sure i'll have to deal with bezels, multi-GPU setups, and expense but it still isn't in that range of expense.
Is 50" too big to sit in front of? It would definitely go above eye level. Maybe take the base off and lean it against the wall to be a little more comfortable.
Wow, even the 6Gb Titan gpu is brought to it's knees & is getting an average of 20fps when fully maxed. Current generation cards are not sufficient for maxing titles such as Crysis 3 & Far Cry 3. Even SLI/Crossfire struggles. Maybe next gen cards, maybe!
urgh that review made me realise how bad crossfire sucks compared to sli. I'm using crossfire and I do often see 50fps but feel 20fps...........God damn them frame time drivers for the 7990 are much needed for 7970 crossfire users right now.
I think some people out there are getting a little to ahead of themselves, there isnt even a single gpu that can max C3 with a decent level of AA at 1080p, and somehow people have gotten the idea into their head that the current batch can push out 4K res even in multi-gpu configuration.
The drivers are coming in June. Why don't you use VSync? It eliminates microstutter, you get smoother gameplay even if there was no microstutter (due to syncing), you would not overwork the cards if they ran over 60FPS (they'd be capped), and you don't dip below 60FPS (since multi-GPU AFR setups work inherently similar to Triple Buffering, which keeps up FPS). Minimize input lag by capping FPS to 60FPS using an FPS cap with MSI Afterburner or RadeonPro, and there you go. Win-win-win-win situation IMO. If you're still worried about VSync-induced lag at this point (you should be facing VERY minimal lag at this point), then you should also know that any microstutter fixes, from AMD or Nvidia, add a frame of delay in order to smooth things out. This means that if you were thinking of running with VSync off and microstutter optimizations on, you will still get that frame of lag you were running away from with VSync. Limitations of AFR. So try VSync and see how it goes.
I wouldn't be interested in one until they can push 96-120 hz !! I was chatting with my buddy about this topic, I hope display resolutions continue to evolve like this- I'd rather see higher resolution at this point than higher 3d quality. Optimization for more detail would be fantastic !
I use radeon Pro and do not notice any micro stutter, that doesn't mean you wont but i dont notice it.
4k gaming or hell 4k standard is LONG WAYS AWAY for gaming never mind Consoles. I say 5 years at minimum maybe more before it becomes standard
There is no microstutter when using RadeonPro with the proper configs. It's not about if one notices it or not; it just isn't there.
And I play games on the moon all day and all night. Come' on here we are pro, microstutter whenever you like it or not there always was, still is and will be forever with mGPU+AFR. It's just reduced with RadeonPro and DFC+TP+Vsync
THANK YOU!!! In some cases, maybe a lot more than people think Vsync (even with triple buffering) can make micro stutter even worse. As the game engine is trying to sync the frames but those "runt frames" are still there are at hardware AND driver level the cards just simply are not synced. Using dynamic frame rate control or capping frame rates, and increasing pre rendered frames can help but then once the stutter is gone you will get mouse lag more than likely. AMD need to adopt it into a hardware level like Nvidia has done.
I talk from a practical perspective and not from a theoretical one. If the frames are perfectly synced, with each card outputting a frame every 16.67ms, with the other card half-done with the next frame, how is there practical, let alone any theoretical microstutter? Yes it does. I am at 60FPS with VSync off and there is immense microstutter. I enable VSync and it's completely smooth, as smooth as a single card. If I gave you a frametime graph, with FCAT, it would be a straight line, and there's no reason it wouldn't be. I am below 60FPS with VSync, again, immense microstutter and observed FPS is below 30. I enable RadeonPro OSD and toggle VSync on. Suddenly, observed FPS matches raw FPS. I'm not blind. EDIT: CPC_RedDawn, that doesn't make sense. Runt frames don't work that way. Runt frames are a result of lack of frame pacing. They are real rendered frames, and this can be proved. A benchmark that runs at slightly higher than 60FPS and exhibits runt frames can be VSynced to a constant smooth 60FPS where no frames are dropped. The frames are displayed. For anyone who disagrees, this is personal experience and extensive testing and others have verified it. So don't discuss it if you didn't try it.
We'll discuss what ever we like. And that's great you believe personal experience somehow applies to everyone. Vsync does not eliminate microstutter. That is a fact. Frame rate capping can do a lot to minimize it. You can argue with Nvidia and AMD about it.
I use both VSync and frame-capping. It applies to every single game. I'm telling you I feel the microstutter with it off, then with it on I can't distinguish the feeling from a single card. Then you tell me "you believe personal experience somehow applies to everyone". So basically another person with the same setup as mine, using the same settings, will be getting microstutter? Should I start writing peer-reviewed articles to please you? EDIT: Frame rate capping reduces microstutter by reducing GPU usage. VSync does the same, above 60FPS.
Indeed. Combined with frame rate capping. Vsync alone does not eliminate microstutter. That is what I took issue with.
Oh, fine. Maybe alone it doesn't. I always use a cap anyways. However, I still get greatly reduced / eliminated microstutter below 60FPS, VSync on, while the FPS cap is at 60FPS. Also, this article (that convinced me to go multi-GPU): http://www.tomshardware.com/reviews/radeon-hd-7990-devil13-7970-x2,3329-11.html Used Dynamic FRC for AMD cards, eliminates microstutter. No VSync involved (shouldn't they call it Dynamic FRC and not Dynamic VSync?) Used Adaptive VSync for Nvidia cards, eliminates microstutter in the places where the GTX690 was achieving those 60FPS. Wouldn't this imply that Vsync and FPS capping both have the same effect on microstutter, at least when FPS is above the FPS cap / refresh rate?
I also use frame capping, but no matter what you say someone will see it differently...which is why I say I dont notice micro stutter i'm sure others will say its there.
