P3D ver4 a Super performer

[Guest]

I can't add much to this as I'm still in the process of performance testing and only recently got my main FS rig back up and running with some new water cooled radiators and water block for my single Titan X Pascal (with stock reference cooler I was peaking at 97C which would trigger throttling and of course stutters).  Now my peak temps are much improved 34C - dual loop setup so GPU has a dedicated loop with a XE 480 radiator (double thick 4 fan rad).

I must admit, I'm a little puzzled by nVidia's "boost" technology, there seems to be an initial period where setting OC boost level works, then after about 5 minutes the "boost" settles back down to base clock even when temps are more than acceptable at 34C and "load" hasn't changed (well below any throttling/protection triggers) ... which is a shame, because the boost levels when "active" changed my avg FPS from 52 to 57 (unlimited no vsync), however when the boost levels drop back to stock my FPS drops back to 52.

Setting 8XSSAA at 4K res does increase boost levels and FPS remains the same (even in clouds, which is good).  Still experimenting, I'll do my prepar3d.cfg shadow adjustments to increase quality and see what happens, that usually puts extreme loads on the GPU when lots of AG present so it "should" trigger high frequency values.

Cheers, Rob.

Rob- You can set the clock to run at the boosted level all the time. You've got the cooling in place that would permit this on a continual basis.

Hi Mark,

I've been trying to do that, but so far NOT successful ... I'll keep researching it, any hints welcome.

Cheers, Rob.

I did this on my Titan Black a while ago and never broke 73c on air. I went back to auto because I really didn't notice any difference except temps went back down to 65. However, I don't run autogen (buildings or trees) and scenery is normal. This is of course not the norm for the majority of folks I suspect.

 

Cheers,

On the whole, the performance I'm seeing is definitely above that of P3D, I'd guess by about 20% in most areas.

However, I *am* still seeing stutters, even with a plain-Jane install and no sliders past halfway,   In that configuration I can get 70+FPS over Chicago, but it sill jerks down to 50 for a frame or two every 5 to 10 seconds.

It's a little irksome.

Stutters here and then slideshiw after 5 min 

I7 4790k 

2x titan sc 6gb each

Was fine in v3.4

Not for me hehe

my gtx 970 and 2500k 4 Ghz is overwhelmed

Same setup except my 2500k is at 4.6ghz.

Ran fine for me. 60FPS in normal load areas. I've always seemed to have more luck with performance than others though.

I pretty much max out XP11 as well except for ground scenery shadows.

Looking forward to guide updates on your website.

It looks like I solved my stutters.   I went poking around at the system level once I was still getting them with settings pared way back.   It looks like an NVidia driver upgrade had tweaked the power saving on my 980Ti, setting it to "optimum power".   I set that back to maximum performance, and set a limit of 4 pre-rendered frames while I was at it, and now things are a lot better.

Now with most settings one click from far right, I'm getting a pretty solid 30FPS over Chicago, and much higher out in the boonies.   And it's gorgeous now that I have all of my FTX purchases installed.

Much happier now.

What is Swap memory and why is it so high?

 

Swap memory is what the computer memory uses when it runs out of physical memory/RAM...

 

It is essentially a file on disk used as memory (that is why it-s *extremely* slow compared to RAM.

 

Per the screenshot, he only ha 8GB, and lots if being used, which is why the computer, probably needing lots more for other stuff, is recurring to swap memory...

My card is reference, not EVGA so don't see the K ... might explain a few things.  Anyone not of overclock Titan X Pascal tools that aren't tied to specific vendor cards?

msi afterburner?

Cheers, Rob.

Really , once you load it up with complex add ons, then you will be able to judge how it performs. 

You are one to talk! Love to tell everyone you have never had an OOM. But you always fail to mention you never set anything high enough! Tunnel vision!

[mikeymike 362]

Anyone else getting  a slideshow and bad stutters?

Hard to see why any of that is either encouraging or impressive.   I guess if you have the hardware to run it there will be some improvement, but indeed, let's get PMDG NGX in Orbx FTX regional scenery so we can really see what's there--the rest of this is hardly valid as a comparison until the full gamut of addons are installed.  I'm sure it will get better especially w/ the highest end graphic processor, like GTX Titan Xp, which is in my future just prior to the divorce paper filing...

I love how clouds and weather have minimal impact on my performance. Only used the included themes so far, The thunderstorms didn't even cost me a frame (running 30hz) 

It sure looks like a bright future :)
