60Hz HDMI 2.0 and my Sony 4K monitor and 970 GTX ... impressed!

Recommended Posts

Thanks for the exhaustive reply Rob - very helpful. I suppose my one remaining question is therefore "what was the two options you disabled in Vector to give the performance improvement you got?"

That's the last one, I promise!

 

TIA

These (wetlands and frozen lakes): http://www.robainscough.com/P3D_Orbx_Vector_Settings.html  I don't want to call it a performance improvement per say as it didn't really impact FPS (on average) but it did remove considerable stutters (long frames).

 

Cheers, Rob.

One should point out that the frozen lakes setting is buggy and ORBX has recommended more than once to disable it.

Rob, thanks for all of your effort on this subject.  I'm just wondering something, though....I've never used P3D and I'm running FSX with the usual xxxxx/NickN tweaks.  I have just purchased a 970FTW card and was interested to know if you have a feel for how much difference there might be when running FSX compared to P3D?  I was looking at getting a 32" Acer 4K IPS monitor or maybe something larger (Phillips 40").  Computer is at 4.4GHz. .  I'm currently running a 28" at 1920 x 1200 and would hopefully see an improvement.

 

Also, based on what you've discovered here, I would assume that I would be in pretty good shape to run at 2560 x 1600.  Is that correct?

 

Thanks to you and anyone else for any comments on my questions.

Hi Jeff,

 

Going to 4K will induce about a 30% performance drop as you are having to process about 4X more pixels.

 

In order to compare to FSX, you have to disable many of the new graphics features in P3D (volumentric fog, tessellation, HDR, etc. etc. -- these are all GPU intensive tasks) ... in doing so you basically force P3D to be CPU limited like FSX is ... so in this particular "skewed" situation I was getting about 25% improvement in FPS using PMDG 777 as the test aircraft at KSEA (default).

 

Unfortunately many people that come from FSX to P3D just crank all the sliders to Max and enable everything and expect better FPS than in FSX -- this just does NOT happen -- and then those folk get disappointed and it spirals downwards from there.

 

P3D Volumetric fog is a triple pass process for the GPU, so very tasking, tessellation is a DX11 exclusive and also very GPU tasking, shadows (clouds, simobject, buildings, veg, terrain, etc.) are also GPU tasking so they add another load of work.  For example if we pretend FSX was coded for software tessellation because it's not supported by DX9 API, FSX FPS would drop drastically (about 60%) ... that's because it would have to be CPU bound since DX9 API doesn't support hardware accelerated Tessellation.   However, in P3D DX11, enabling Tessellation has a far far less drastic affect on FPS (in my case <5% drop) because it's very GPU dependent (newer GPU's handle Tessellation with easy, older GPUs not so well).

 

Cheers, Rob.

This probably a better monitor then the Phillips VA monitor - Perfect Pixel WASABI MANGO UHD420 REAL 4K 42" LG AH-IPS Panel UHD 3840x2160 HDMI Displayport 42 inch Monitor.

It has pretty good reviews on overclocker.net. http://www.overclock.net/t/1554580/got-a-wasabi-mango-4k-42-korean-ips-monitor-what-tests-to-run

 

I am thinking about pulling the trigger on this !

Strider1, thanks for the lead.  That looks like a good deal.  Earlier today I bought a Samsung UN48JU6700 48" 4K TV and then picked up an EVGA 980 Ti Superclocked+ ACX2.0+ video card to go with it.  Will try it all out tomorrow.  The TV came through a recommendation from another AVSIM person, "Overload", who has had great luck with it as well as the 970 card for 4K.

I haven't read this whole thread but it seems you have the B series sony 4k TV. I have the new 850C 55" 4K. When you look in the documentation it states 30fps @4K: 

 

  • HDMI PC Input Format : 640x480@60Hz; 800x600@60Hz; 1280x768@60Hz-R; 1280x768@60Hz; 1360x768@60Hz; 1024x768@60Hz; 1280x1024@60Hz; 1920x1080@60Hz; 3840x2160@30Hz

Kind of confused. I have two of the fancy AudioQuest Cinnamon HDMI cables for using ARC http://www.audioquest.com/hdmi/cinnamon

 

Edit. Maybe I should read the whole thing:

 

  • Video Signal : 3840x2160/24p (HDMI only); 3840x2160/30p (HDMI only); *4096x2160/24p (display center 3840 area); YUV420 3840x2160/60p (HDMI only); *YUV420 4096x2160/60p (display center 3840 area); 1080/24p(HDMI only); 1080/60i (HDMI, Component); 1080/60p (HDMI, Component); 480/60i; 480/60p; 720/60p; 1080/30p (HDMI only); 720/30p (HDMI only); 720/24p (HDMI only)

No problems running my B series at 60Hz @ 3840 x 2160 without any image quality reduction here (using YCbCr "limited").  But my monitor has also gone thru 6 auto firmware updates since I purchased which could supersede the listed manual/pdf specifications.

 

NOTE: in order to get 60Hz support/optioni from nVidia I had to install the 3D Vision components.

 

Cheers, Rob.

hi

 

I currently have a i7 2600 cpu with a Nvidia Gforce 550 GTX do you think I will see much improvement in FSX if i uprade to this card using windows 7 64 bit ? 

 

p.s should have added that the resolution I will be playing with is 1080 x 1920.
