And that will obviously impact your performance will it not?

 

I better post my NGX video then ... you'll be back at the store getting the 4K monitor and a Titan X.

 

Are your settings higher than this?  http://www.robainscough.com/P3D_Titan_X_4K_Set.html

 

FYI ... you need minimum HDMI 2.0 cable that can sustain 18Gbps, HDMI 1.4 cables may not be up to the task.

 

Cheers, Rob.

Great post WebMaximus. I have a 780ti presently and am also going to purchase a 980ti when available.  According to Guru.com the specs looks like it will have a faster clock speed than the TitanX with 6gb or 8gb of memory.

 

I remember when I got my current Titan and not long after that the 780Ti was released and found faster in most reviews as I recall it, at least for normal gaming purposes. I remember thinking that at least I had lots of memory on my Titan but since that never came to any real use in FSX and running at 1920x1080 I though this time around I will try convince myself not re-doing the same mistake.

WebMaximus, I've not monitored my 980 GPU Load in different situations, but will give it a try. I've not kept track of what works when. I kind of just go with the flow, making adjustments when needed. Sometimes there's no rhyme or reason to what will work. Not very scientific I suppose but that's due to the lack of consistency I often find in the operation of the sim. Of course, weather and AI could have a lot to do with that, not to mention various add-on scenery.

Hmm...not sure I want to see your NGX video :wink:

 

A little bit hard to compare the settings since I have some stuff enabled that you don't like some of the shadow options while you have some other things I don't such as a higher LOD. I posted my settings a couple of posts ago in this thread.

 

I remember you (or might have been someone else) pointed out the importance of using a proper HDMI 2.0 cable so I did get one of those capable of a transfer speed in excess of 20 GBps if my memory serves. However Robert informed me my GFX card is a HDMI 1.4 card so guess then what cable I use won't do much of a difference.

 

Maybe 8K screens will hit the streets approx at the same time Nvidia launches a 980Ti so I guess that might be a good time to grab a 980Ti and a good 4K screen maybe for half the price compared to today :wink:

 

 

After some investigation I found that when running unlimited frames in P3Dv2.5 the GPU load stays at 100% all the time which led me to the conclusion that running unlimited frames will not leave any headroom for the GPU meaning when you enter a situation where the load will increase even further the GFX card can't cope with the load and hence the stutters and FPS drop.

 

The 100% GPU load should ONLY happen when running SGSS AA ... not really related to P3D, any 3D application will do the same with SGSS AA.  The only way to reduce that GPU load is to not use SGSS AA. But I am curious, do you think the AA looks bad (or not up to your desired quality) in that Dubai 4K video I posted?

In my case the only way I could get the GPU load to drop rather than staying at 98-100% constantly was to lock the framrate. Sitting in a cold and dark NGX at a complex airport such as FlyTampa's Copehagen with ASN running I've seen my GPU load been between 60-85% or so. Not sure what it is causing the load to sometimes be approx 60% and sometimes 80% or so but at least I'm happy it's not stuck at 100% anymore.

 

Will try to do a flight now rather than spending all my time in here :wink: but will check your video later tonight and let you know what I think. Should also repeat that when I tried out the 4K screen the problem was certainly not the IQ, it was actually rather good even with no AA at all. What was my problem was that the smoothness was not there running in UHD resolution.

Rob, my experience is different and I'd appreciate your input. I don't even know what SGSS AA is, although I suppose it's a graphics setting found in the nVidia Control Panel or nVidia Inspector. I don't use nVidia Inspector and my nVidia Control Panel uses the default settings.

 

Yet, while I don't monitor my 980 GPU usage in various situations, I have monitored it in general and I have noticed that it often runs at 99%. I couldn't tell you under what conditions, however, as I've not monitored it that closely. It's partially because of this that I've ordered a TitanX. 

 

So, I just thought I'd note that 99% usage, in my experience anyway, is possible without using SGSS AA.

 

Please get that 737 video posted. I can't wait to see it.

Aaah, FT's Copenhagen, I suspected as much based on your sig.  Pretty sure FT Copenhagen uses ASM methods which are not supported in P3D ... I've not had much performance success at Copenhagen ... FT's Dubai clearly has considerable more complex objects (especially the surrounding area) and high quality textures but doesn't seem to suffer on the performance front.

 

I'll do an NGX flight out of Copenhagen with ASN, but my hunch is I'll OOM at my current settings before I get too far.  I'll need to run my complex aircraft settings (usually means drop textures down to 1024 and dial a few other options back).  I'll report back, but I'll be surprised if I can sustain the same fluidity as Dubai.  Odd, Thessaloniki was done by the same developer and it's performance with surrounding area is outstanding.

 

Cheers, Rob.

I'll need to know all your settings to be able to provide any useful comment.

And that will have to wait till I'm next at the simulator. But will do later today or tomorrow.

 

Thanks,

One further thought that qualifies my previous statement that you need a video card with HDMI 2.0 to fully address a 4K monitor.

 

What I failed to mention—and I'm pretty sure I'm correct about this—is that if your video card and 4K monitor both have DisplayPorts, then you're set to go. So some pre-900 series cards may fill the bill. I never got to explore this path because my monitors had only HDMI 2.0 inputs.

Well I discussed this and I think it's data related see my post link below on the Fly-tampa forum .

Copenhagen is one of those places ;-)

Yeah, reason I used FT's EKCH in this example is that's one of the few airports I've installed so far since I switched from FSX to P3D but I understood EKCH indeed is hard on your system. I also experienced the danger of getting OOMs there, when I landed I had some 250 VAS left so that was a real close call but luckily I managed to complete the flight all the way into the gate. I think I improved things a bit now by renaming the Copenhagen City BGL.

 

Just climbed through rather dense clouds on my way back home to ESSA and I'm happy to say it looks like my downsizing of the HDEv2 clouds have done some good because I didn't experience the same amount of stutters now but still with 4xSGSS. I think the way it is now I can learn to live with until there is hardware capable of getting rid of the issue all together.

Would have tried this if I had knew by that time before I returned the 4K screen because I'm pretty sure my Titan has a DisplayPort and I think the 4K screen had one too.

 

Oh well...

Did you visit the fly Tampa forum for some performance updates make sure to disable the AES traffic which is enabled by default...

Don't have OOMS at EKCH with 737 or 777 see shot of my config below ;-)

 

 

 

 

data related see my post link below on the Fly-tampa forum .
Copenhagen

 

Could be, I know Dubai is remote but it still has considerably more objects to render than Toronto and/or Copenhagen.  I have a hunch there are objects being rendered that aren't visible in Copenhagen ... with Toronto I think it's just too much airport too close to a major city.

 

I'll try your settings though, think I'm pretty similar.

Thanks but I already have them disabled.
