bought a 4k monitor, poor performance

Recommended Posts

I bought a samsung 4k monitor and was so stoked to try it out on P3d v3.4. I wish I had not bought it, I went from 30 FPS down to 16 FPS. I am running a GTX 970. I didn't know that it would cause this much of a performance hit. Am I out of luck with this or can I squeeze some performance out of my 970?

 

Please help

Did you do a fresh clean install of your video driver?  ditch any NI profile settings you don't need it. you should be getting 30 to 40 fps in most areas with a 970. What speed is your possessor.

sorry for the lack of info everyone, i honestly didnt know what you all would need.

 

i upgraded from a 23 inch 1080p monitor to a 28 inch 4k monitor.

 

i have not done a frsh install of drivers and i actually never used NI for my p3d v3.4 switch from FSX. (i switched last christmas to p3d v3.1 and have upgraded to each version when they became available.)

I'm just guessing but if you only changed the monitor from a 23 1080 to a 28 4K you should not have lost half of your frames. Some fps lose was to be expected since you are pushing more pixels thru you 970. But I'm at a loss why you would lose half of your Fps.

 The size of the new monitor or TV will have ZERO effect on the fps. 4k is 4k, it's the fact that you are going up in resolution by 4x over what you were running before. That being said, did you reduce the anli-aliasing that you were running on the 1080 monitor as you won't need much if any with 4x as many pixels on your screen.

heres an update for everyone. I dialed back some settings in p3d like tesselation from high to low and changed cloud draw distance from 90 to 60. I also only have FXAA and 2X multisampling AA enabled and it has brought up my performance to what I was getting before + or - 2 or 3 frames.

 

The only issue now is performance with clouds and my first time having OOMs. Would going 4k increase my chances of OOMs? it seems it has.

Which version of Windows are you using?  Win 7?

W10 64 bit (not the anniversary update)

processor is an old i7 2700k OCed to 4.6

Check to see if you can change the actual display input settings using the TV remote.  I changed the input on my LG from HDMI to "HDMI PC" and it made a difference.

Set your frame rate in P3D to 60, then try each of the hdmi inputs in turn with a fresh start of P3D.  I had the very same issue going to 4k until I found the 60hz input on the TV.  Now getting 60 fps all the time. Just don't get frustrated.  Be logical and don't fool around with changing all the settings in P3D until you get the right TV input.  Hope this helps

Still a great processor, especially for FSX/P3D, however with the motherboard used for these processors any overclocking of the processor is more prone to creating CPU/GPU bottlenecks (later i7 processors/motherboards are less prone to this).  This may not be the case with your setup, but it's something I'd recommend you evaluate and adjust your settings if required.  NOTE:  This would not be causing the majority of your issues, file this under "system grooming".

Robert is spot on.  Depending on the TV, you should ensure you have PC=HDMI or PC.

 

GREAT INFORMATION

 

Rob Ainscough has done substantial test and evaluation of P3D/4K Settings and published his results in THIS THREAD, so I won't bother (or insult Rob) by re-typing it.  It's worth reading the ENTIRE THREAD, start to finish.

 

YOUR 4K TV SPECIFICATIONS

 

I might have missed it, but would you please repost the Make and Model of your 4K TV?  Also a link to the specifications, if you have it.

hello,

 

i actually bought a specific 4k moniter. im using display port 1.2 so i can get 60hz refresh rate. the model number is samsung u28e590d. Ill look at the thread you mentioned sometime today or tonight. Thanks for helping!

Ah... my apologies my friend!  I missed that entirely!  That being the case, 'm not sure the info I provided will be of much use to you - though it could be, I have no experience with 4K monitors and their settings.

 

One thing I might suggest is to delete your shaders (they'll be rebuilt on a subsequent load).  I'm not sure if this was already recommended.

 

I'm very interested to see how you make out, and to learn the differences between a 4K TV and 4K monitor, and I'd love to know what settings you have available.

 

Best wishes!

ill keep this thread updated. as of now, 4k on a smaller 28inch screen is fantastic. i really only need fxaa on and nothijg else. its an amazing experience, flying and computing in 4k.

I just plugged my in, did a few settings and go.  The only thing I needed was MSAA at 4x and anisotropic at 2x.  I tried the 30Hrtz and v sink tweak but on my system it seem to made performance worse so I am leaving it at 60 hrtz for now and do some more experiments later. If anything I'm getting better performance than before. Hope you can get it worked out.  Josh

 Did you leave off AA within the sim?  My 4k tv should be here in a few days and I'm trying to find a starting point for my settings.

Interesting....I have a 22inch monitor and looking to upgrade to 4k. Will bear this in mind.

i have a 4k tv and i decided to go with a computer monitor for the smaller size. it seems more clear to me as well. I assume thats because the physical size of the pixels are smaller. upgrade to 4k...its worth it.

 

My other advice is to inveat in a gtx 1070 or other comparable card. My 970 does fine in very light weather conditions but cant hold up in bad weather.

Matthew,

 

Are you using an OS "size" ... I think Windows 10 (older verison not anniversary) would automatically set font/text/app sizing to 125% or 150% ... this could cause FPS issues in P3D.  Reason I ask is that many people with smaller sized 4K monitors often use the font/text/app sizing to increase size as to make it more readable and not so tiny on a smaller 4K monitor.

 

If so, try setting to 100% so no scaling.  Also per my P3D Guide, there is a table showing you what to expect when moving from 1080p to 2160p ... about a 21% performance drop but this will vary based on CPU/GPU ... does your 970 have 4GB VRAM or 2GB VRAM?  In your case, I'd suggest the bottleneck is your CPU ... best way to test which is the bottleneck is to use EVGA Precision X to monitor CPU and GPU usage during flight in P3D with and without clouds (just make sure you test with consistent weather themes and not 3rd party weather engines).  If your CPU is maxed at 99% then it's the CPU, if your GPU is maxed at 99% then it's the GPU.  If both then you might want to look at a system upgrade since you're pushing 4X more pixels -- 8,294,400 pixels that must have their color set per frame ... so at 30 FPS that would be 248,832,000 pixels changing every second vs. 1080p which is 62,208,000 pixels changing every second.

 

I like to break it down into actual numbers because I think it's important PC users understand just how much processing is happening in a very short period of time.

 

Cheers, Rob.

I tried scaling down from 150% back to 100% in windows and it killed my FPS to about 6 FPS. I have been testing and it looks as if my CPU and GPU are pegged at 99%. They both are pegged at 99% on my old monitor at 1080p as well. Everything is good in terms of FPS but the default terrain loads slowly if at all. I pan down and it looks like the terrain that is 100 plus miles away. It's just blobs of color. I have the i7 920 OCed to 4.8 GHz and the 970 is the 4GB variant. Oh well. Ill give it a couple of weeks and if things don't change, I'm going to return it. Ill maybe wait until next year and purchase a 1070 along with the monitor.

 

If there is anything that can be done on my end, let me know.

Hello Dave,

 

Yea I read to much into the post and related it to my upgrade from a 1080p to 4k. I ASSUMED he went from a 1080 to 4k and went bigger. But yes you are on point resolution is the key. Hope I didn't lead anybody astray.

looks like orbx stuff really messed up texture loading for some reason. every thing seems fine again after uninstalling it.
