Is Freesync going to make a lot of difference at 30-60fps? I plan to get the LG 27UD68P-B.

Im running an R9 280X and will upgrade to the 480 once it releases and might CF if it scales well. Hoping to play 4k at medium 60fps. (High if CF)
else ill just get a Dell P2715Q which would be abit cheaper.
I'm uncertain if freesync works in crossfire. AMD claims better multiGPU support but we have no idea what shape or form that will come in, could result in ONLY DX12/Vulkan games, which I can count on 1 hand atm!
hmm... yeah true... So is Freesync worth it? Else ill just settle on the Dell. Anyway I live in Singapore so im not sure if the LG has international warranty...
I dont experience much screen tearing on my 1080p monitor, or maybe I just dont pay enough attention to notice it. How often does screen tearing appear? (I play CS:GO, Fallout 4, Overwatch and some DOTA 2)
I am going to go ahead and tell you that 4k at ~27" is not a great move. I have a 32" 4k monitor, and can't imagine that any sane person would want the pixels any smaller. Windows has terrible UI scaling and in game menus and stuff do as well. You are much better off by looking at 4k monitors that are 32" or larger. The Korean model that Wendell just reviewed which has an LG panel would be the one I would be looking at should I be in the market right now. I don't know how that fits into your budget, but I would consider getting anything smaller to be a waste of money since you either won't be able to see text and things easily or are wasting real estate by scaling the UI. Or, you could have amazing vision or love to touch your nose to the monitor.
About the gpu situation. If you are playing games at 4k with a 280x, you won't be hitting 60fps. Maybe in games like DOTA and CSGO, but games like Overwatch and Fallout 4 will not happen without turning settings WAY down. I should know, I have a 280x and a 4k monitor. If you are planning on playing at 4k, you will also want to look into something more powerful than a 480. That won't cut it, I don't imagine. I would wait for Vega for sure. Maybe even Navi. The current speculation is that the 480 will perform on par with the Fury in a best case scenario. That simple isn't fast enough for 4k gaming, unfortunately.
Now for the question of freesync at 60fps. With 4k, I would say that it is definitely worth it. High resolutions like 4k is where freesync makes the most sense. Lower resolutions, it will be much easier to have the game pinned at 60fps with vsync on. 4k makes it nearly impossible with modern games. I expect that in most games, even with the settings turned down, that you will have a good bit of time spent below 60fps at 4k. This should make stuttering and tearing much more evident. As it stands, a 280x at 1080p is a good combination. I was getting very nice frame rates with my 280x at 1080p, usually very stable and mostly above 60fps. In that situation, freesync makes less sense as you would likely run across stuttering and tearing much less often. So yes, it make sense to have freesync at 60fps if you are at 4k.
Curious thing from these syncs, once you force vsync off from everything it will reveal which ones are just so broken that there is clear cut in middle of screen, top & bottom part are 0.5s out of sync. :D
Overclock it using CRU, most 60hz monitor can go up to 75hz.
Freesync is not just for high framerate. Actually it works just fine with lower framerate as well.
My advice would be get the freesync monitors, get 480 if you wish, and then just wait for Vega. Otherwise find 295x2 and you will have basically 480 CF...
In theory yes, when it works, you can go down to 50fps before things start to look choppy.
but in reality, NOPE, games and drivers are horribly broken and just having freesync enabled will cause a shit show.
Source: I own a 27MU67 and Fury, 390x, when freesync was enabled games that should have been running at 120fps+ (witcher 2) where giving me 40fps~ major frame time and stutter issues, had many problems with other games too.
disabled Freesync on the monitor and presto everything worked fine.
Its horribly broken atm
I'm going to have to call you out.
A 4k @27" is bloody amazing, source, LG 27MU67, crisp images, and windows DPI scaling works, and can work very well if you know how to configure it (enable scaling, then disable it in compatability settings in an app by app basis to remove the aliasing)
B gaming at 4k, either the games run like a dream (dota, csgo, etc) or are an unplayable mess even with powerful GPUs (Witcher 3, metro etc) in some cases even putting the settings to minimum wont cut it
C read my previous post, freesync is horribly broken from my experience.
I've read reviews where people claim that it works just as well as G-sync, no major issues at all. Perhaps there is something wrong with your monitor? It seems strange.
it "works" in some cases, but for many games its extremely broken.
and in those cases you're better off lowering setting a tad to get an extra 5-10fp (anything below 50fps is choppy and freesync can't save it)
Could just be the implementation in the monitor that you have. It shouldn't be "choppy" after getting below 50fps unless that is the low end of what your particular monitor supports. Freesync theoretically supports all the way down to 9fps.
That thing is on sale for only $400 at massdrop right? It's going to be the cheapest thing you can find anyways.
but I don't think the 280X supports free-sync man, but the free-sync there is just a nice bonus
and ya the 280X doesn't support free-sync for games because it was an actual rebrand of the 7970, doesn't have display port 1.2a, but that's a pretty good display anyways

"The AMD
Radeon™ R9 295X2, 290X, R9 290, R9 285, R7 260X and R7 260
GPUs additionally feature updated display controllers that will support
dynamic refresh rates during gaming."
That isn't an issue with free-sync, you're having some major issues elsewhere if your fps drops when you enable free-sync, or there's some setting somewhere you missed causing that
Also is that the original display or the "-B" update of the display? there might just be a firmware fix for you, and why there's a newer model
hmmm, its the regular version I think, and it doesn't support usb firmware updates sadly.
If it's still under warranty you could probably contact LG
I don't want to ship it. sRGB mode works flawlessly (and has freesync greyed out)
I'll email them to see whats up, but I'm not going to ship the bugger.
below 50fps, the low refresh rate is apparent, similar to capping your games at 30fps. sure you have even frame pacing 1 frame per 2hz, but its still choppy.
IF your complaint is literally just that 50fps is too low for you, then freesync won't help you.
No, my complain is that freesync is a mess with some games and will give you worse performance than if you stuck to conventional vsync.
And to add to that, freesync is only effective if the game is hovering around the 50-60fps range, since anything lower will feel choppy and bad regardless of freesync or anything else, just due to the fact the image difference per frame its large enough our eyes stop perceiving it as fluid motion.
and when you're in that range, you can easily forgo freesync and drop the games settings a bit to nudge your self over the 60fps range.
