4k Philips Monitor 40" at 60hz

[BitMaster]

Are you using some kind of monitoring tool to show how much VRAM you are using ?

 

I believe what you say but I also believe what my monitoring tool says and there is a gap between those 2 truths haha :)

 

Are you running any mods ?

[PureEvil]

sort of bad example: just 1 plane in the mission. nvidia control settings set to "let the 3d application decide", then dsr set to 4k, smoothness 0%. in-game high settings, no hdr, tsaa. vram usage about 1800MB. no mods.

[Kuky]

Anything with 12GB VRAM will work for 4k, anything below will be a SHOWSTOPPER :)

 

Bit

 

Not at all, I have GTX980 with 4GB VRAM and its enough for 4K resolution.

[BitMaster]

Oh well, I am glad that my Asus tool led me to a wrong conclusion.

 

I then wonder what that tool tries to tell me with that much VRAM usage.

 

I use Mustang's shader and cloud & terrain mods, MoreVisibility mod set to extreme, and a bunch of others but I dont think they change anything in the planes I tested it in, those were untouched, MiG 15 and 21.

 

 

Has anybody seen how that Asus 4k screen performs ?

 

I need a 2nd one for work and I thought, ahem, well guess :)

 

Bit

[BitMaster]

BTW, with MoreVisibility set to Extreme, well it really really looks nice and gorgeous BUT it's also a big fps drop. I can easily force the card into the 30s now when I fly low over certain terrain, just high enough to have a 30mile view.

 

I love that mod so much, I rather get a 2nd 980 than deinstall the mod :)

[six.dof]

I got mine yesterday (650 US$) first run I was a little bit disappointed, as the picture looks not smooth and somehow muddy, after short Google, standard setting is Displayport 1.1, after change to 1.2 ( on the monitor), perfect, before I had a 27" 2560x1440, what was not bad.

 

I run standard DCS on a i7 2600k@4.2GHz, 16GB, sapphire 280X/3GB, interesting is that the fps not much less as on the old screen.

What makes me relaxed to wait for the new AMD graficcard generation, which hopefully be available in the next 6 months to acceptable prices.

Acer XB280HK bprz 4k with Gsync, read the review, excellent.

[Chief1942]

Just pulled the trigger on the Acer XB280HK bprz 4k with Gsync monitor. Once I've got it and had a chance to get it up and running, I'll provide my impressions. Should be about 4-5 days.

[BitMaster]

great, as I am i the need of a 2nd screen and need some facts....

 

From all reviews I read, none suggested a single 980GTX for 4k, they all say for 4k you better go 980GTX in SLI. OK, for some not-so-3d-heavy games 1 gtx could be enough and some here also say so but I think, regardless what others stated, 4GB is too small for 4k and the 980GTX needs some more juice to satisfy as a GTX on 4k. SO I really look for a good 4k screen to work on and MAYBE play some easy games in 4k for not more than 500 € w/o tax.

 

Bit

[Chief1942]

DCS can be an expensivee past time!

 

Not sure how my tests will work for others once the Acer arrives as I have a new NVIDIA GTX Titan X on the way as well:cheer3nc:. Should be pretty much ready for DCS 2.0 now!:joystick:

[BitMaster]

great !!

[BitMaster]

The Titan X should keep your FPS well inside the dynamic range for Gsync to work :)

 

Just found that out, mine has 50-144Hz so I have to be ABOVE 50 fps to make Gsync work, same with FreeSync.

 

They both depend on being INSIDE the monitors dynamic range.

 

So, such a Monitor and a card that only pushes 30 fps is a show stopper.

 

What a shame, as 30 fps range is where Gsync and FreeSync would help most. You then need a screen with 20-100Hz DR or similar, jus that those will never have Gsync I guess.

 

Lets hope for Adaptive Sync by Vesa, free of license issues and should then work with all new monitors....in a couple years.

 

Bit

[Chief1942]

SHHHH!

 

If the wife finds out that I keep chasing this "cutting edge" stuff, she will have my head on a platter:music_whistling:. If I sat down and tried to calculate all the $$$$$$$$ I've spent just to stay around the highest FPS in my sims, I could probably have bought myself a private plane and gotten a pilots license;) Been at this since the mid-90's. Currently have ASUS GTX-780's running in SLI and some reviews have indicated that would be sufficient for the new ACER monitor. Can't take that chance so went with the latest "Beast".

There in no such card as for now

[Decibel dB]

I have been running 4K res for almost 1 year at 60Hz with a DP 1.2 cable setting at almost maxed and AA off (no need for it at that res) with all my sim's with and r9 295x2 except DCS. Depending if I play solo or I join a server I can't get enough FPS to dogfight without getting seasick. Just to give an example in solo mode I have a better FPS in 4K then 1080p but in multi-players not. I 've been searching and asking this questions to find a fix. After many discussion I came to the conclusion that DCS hate my AMD card and I cross my finger for EDGE.

 

To answer to BitMaster with Cliff of Dover, BoS and WT with maxed setting at 4K plus one 1080p monitor I get 3.9 Gb usage of VRAM

Are we talking about the Philips monitor of the thread? It's a 60hz

[BitMaster]

Yes, there is !

 

Nvidia GTX Titan-X 12GB

 

 

Well, it might be that for 4k 4GB seems to be enough, I just wonder why all reviews that I read say that for 4k they suggest a SLI setup of 980s or a Titan-X with 12GB, it must have a reason.

 

Also, when I measure my VRAM it usually, as I got told, caches until it's almost filled up, so having more GB than you actually need 1st place is no bad thing, switching back and forth in F2 view etc..

 

 

I am eager to see the VRAM usage of a card with way more than 4GB in the same scene, say fly the same path with 4GB and 12GB, measure fps and VRAM usage. I bet the card with more VRAM delivers the better experience....and, a card can only use what it's got. So if it would actually need 6.5GB but only has 4GB to address, you will never see the 6.5GB usage, whereas the same scene on a 8 or 12GB card may well consume 8, 10 or more GB, just my guessing.

 

I am happy with the 980 and it's overclocking capability and for WHQD 4GB seems to be enough to maintain a smooth gameflow.

 

 

 

The Dynamic Range problem actually affects all monitors, you can only display framerates that are inside that range, anything below or above causes tearing/clutter/what not else.

 

60Hz is the upper value of that range in the Philips case, check the lower value too, that is the number you must achieve in fps to somehow make FreeSync or Gsync work. Switching on Vsync basically locks fps at either 30 or 60 fps, that is how I understood the Guru3d review.

 

This review pretty much explains it all in well understandable form:

I hear you :)

 

I got them a Wii-U so they have something too HAHA....and it works.

 

No, seriously, having the rig is one thing, finding the time to use it a totally different issue that I still have to solve and we also expect a new baby in July, so things get even more complicated.

 

Family 1st, everything else comes with a big distance.

Decibel dB,

According to Tom's hardware, that card you have beats the NVIDIA Titan X in most of the games they used for their testing. I think you are still running the strongest card at the moment EXCEPT for DCS. As you have indicated DCS simply does not like AMD cards as compared to Nividia's offerings, hence my choice of the Titan X. I suggest you be patient and see what DCS 2.0 does for you. I think you will be more than pleased.

[Decibel dB]

Yes, there is !

 

Nvidia GTX Titan-X 12GB

 

 

Oups my bad I didn't know that the Titan X was a single GPU card, Thank you.

 

As most off those monster are dual GPU you have to take the announce VRAM with a grain of salt since they don't ad up, they only mirror each other. Take my card for example they sold and advertise the R9 295x2 as a 8Gb Vram card (2 x the 4GB of the R9 290) but it's not it's 4gb. Two GTX TITAN black in SLI is 6Gb not 12Gb.

I know that is my main reason why I select that one. Your right about that, I am sitting and waiting for EDGE.

 

Thanks for the reply

[Chief1942]

Weeeeeell!

 

I now have my ACER XB280HK monitor and my NVIDIA GTX Titan X video card up and running.

Here's my initial impression:

 

Of course graphics are stunning at 4K.:D

GSync works as advertised.:)

Good luck trying to read the fonts on screen in-game.:(

With these old eyes, I have changed my resolution to 2560X1440:thumbup:

Still looks great and of course improved FPS and I can actually read the script on screen.:) Appreciate that I was on a 32" JVC HDTV so the change is remarkable:smilewink:

 

So far, it is very graphically beautiful but with the price. Perhaps 4K in a MUCH larger screen format, ie. 40 + incher. I have tried all the Windows scaling features but the best res for me currently is way down from 4K.

Perhaps when ED releases DCSW 2.0 many things may change, so will simply accept that I have much more than works for me at the moment and will await the future.:pilotfly:

[BitMaster]

Yahh, I have flown DCS on 2880x1800 on my 15" Mac retina, same experience as you had, you cant read a damn thing !

 

With QHD and 27/28" it's just OK.

 

Whats your average fps in a decent AC like Mig21 Mig15 P-51 etc.. ?

 

I use 4x MSAA but no TSSAA and no civil traffic, the rest is on or maxed.

 

I use Mustangs Shader and Sky/cloud mods and MoreVisibility Mod at Ultimate setting. That gives me 60-100 fps inside cockpit and 100+ external.

 

I really would like to see what the Titan-X can push in default and how close a oc'ed 980 can get :))

 

Bit

[Chief1942]

Bit,

At 4K with G-Sync working I was getting in the low 40's in the P-51 inside the pit and in the 60's outside. It was really difficult to tell as the script in the FPS display was so small I could barely make it out. When I went to the current resolution, primarily so I could read the script, it went up into the 60max inside the pit and in the high 90's + outside. I have a whole mess of mods running including all those you mentioned., plus running ALL the settings in game at max including civil traffic. I am quite happy with this setup as it really is smooth in spite of those times the FPS drops, and I attribute that to the G-Sync. Again, it is worlds better than my previous setup which was two GTX 780's in SLI on that UHD TV at 32". Can really see the distant a/c what with the pixel density and all. Easier to pick them up at distance. All this seems to match up to those that have been down this road before me so I guess that is the "bar" at the moment. Will have to wait and see what DCS 2.0 brings.

you should stop worrying about the fps and just enjoy the game. also you should only compare cpu's and gpu's with stock clocks and without mods, most of us play like that (not me, ok).

 

before edge, it's all pointless searching for a perfect hardware.
