High cpu frame time

[Xthedarkknight99x]

So my replacement rift s came in as well as my new headset.

 

 

Did a little testing with the Reverb and installed the fpsvr app.

 

I noted in the app that the cpu frame time states over 20ms

 

 

how can I bring this number down.. Seems to be constantly high across settings.

 

Cpu is 8700k I usually it at 4.6ghz all cores

 

 

 

My cpu is the oldest part in my computer but it doesn't seem to show wear.

 

Oculus had me test my components and all test came back ok.

 

This could be the reason for a lot of my ghosting.

its kind of difficult to say .. we don't know:

 

- what your settings are in DCS

- what your settings are in Steam

- what the rest of your hardware is

- under which circumstances which set of frame times applied to which scenario

[Gunnars Driver]

AS ^^^ he says.

 

Start by making sure you have the settings per thuds reverb guide on vr4dcs.com.

Follow it Point to Point.

 

DCS pixeldensity should be set to 1. not anything else.

SteamVR supersampling initially set to 100% depending on version, but it should be saying 2207 x 2160).

Set the motionreprojection to auto as per thuds guide.

 

When done, set the initial settings at DCS to rather low values.

Preload radius should be set high (helps with high, at least if youre not too short on RAM).

 

in this thread there is a lot of info: https://forums.eagle.ru/showpost.php?p=4195548&postcount=4983

 

Civil traffic OFF

Heat blur OFF

Shadows Flat only ( or lower)

MSAA OFF or 2x

Dept of field OFF

Lens effects None

Motion blur OFF

MSAA OFF

 

Clutter/Grass - set very low initially

GRass same as above

Chimney smoke - minimum

anisotropi filtering -- OFF or low value.

Terrain shadows - start lowest possible

cockpit global illumination - OFF

disable rain droplets

do not use VSYNC selection

 

 

The VR button has some kind of preset values - Changes all or some of the settings on this page...dont use after you have started tuning.

The other selections not mentioned - start low. If the game runs fine with smooth gaming ie not below 45fps increase settings and take not of CPU/GPU fram time. Also make note of Visual Changes, if you cannot se the difference but the GPU or CPU fram time goes high….maybe not worth it.

My apologies as I am a tad bit frustrated.

8700k 4.6ghz

Stock 2080ti

32gigs 3200 ram

Samsung ssd

 

motion reprojection is suppose to be on but according to the tool it doesn't seem to.

 

One imagine was of steamvr ss 184% the other was 33%

 

 

all i can get right now.. either way CPU seems maxed out even though its showing 33% threat core count.

 

 

This was also performed in a single player basic mission with a few starter AI.

 

 

I will clean up the thread when I can.. However I found it pretty abnormal that lower settings could yield such terrible results on the cpu.

 

Personally think my cpu is busted but thats my thinking.

OK.

 

 

Go follow thud's vr guide, as above to the letter.

 

If you have motionvector set to force, then you will *never* see the reprojection indicator. But tbh,its pretty obvious, without it you will see frame rates between 1-90, at auto, you will see 90, 45 and 44-1 and with force you will see 45 and 44-1 +/- 1 fps.

 

You are not in the current incarnation of DCS, going to use more than 3 cores, so with hyper threading that would put you about right at 33%. My personal recommendation is turn of hyper- threading in bios, but, YMMV.

Again, what Stuartaston says. Do not try to make any shortcuts, not following thuds guide.

There have been some different versions of steamVR reporting different resulotions for 100%.

What is important is to initially try to get as Close as native resulotion as possible to the reverb.

Any slight misstake in this and you might be sitting with some kind of supersampling that either bogs you computer down or makes a bad Visual due to very low resulotion. Because of the different SteamVR versions, we really cannot help if you do a shortcut, getting high supersampling that we do not know about.

The set supersampling need to show a resulotion of 2207 x 2160, that is currently the closest to the reverb native. With the correct version and setting this equals 100% SS.

 

 

Are you a experienced computer tuner ? A busted CPU, still working isnt that common.

 

Things needed to make sure(if not 100% sure, each of these can make a dull day):

 

-For the CPU, make sure it runs at the higher clock all the time(turbo mode is per Intel default a part time job. Set it to your max Clock all the time during gaming. Verify with CPU-Z that Clock stays high. BTW, the 8700K is 4.7Ghz turbo isnt it ? Overclocking is as more or less needed option as the CPU Clock frequency from time to time isnt high enough. OC helps.

 

-Make sure your RAM is set to 3200mhz. Default setting if just mount them and do nothing is probably 2667mhz. XMP Profile or other setting will ensure this. Check this with HWinfo64 or other. (I Think memory freq will come out as half of makred speed, so 1800mhz is correct for 3200mhz(de are double dara rate, so 2x 1800mhz).

 

-Make sure latsest version of win10 is installed. In the info, it has to say version 1909. Period. Among other things, for reprojection to work without problems.

 

Reprojection, you should use "auto". And as Stuart says, you should use the hint from the fpsVR or the fps counter in DCS and make sure it stays at 90 or 45, or maybe less....but it shouldnt hunt up and down and show "any value"between 45 and 90. If it do, reprojection isnt on.

 

I also have a 2080ti, 32Gb 3200mhz. I have a i9 9900@5.2 but it doesnt make very much difference between 5.2 and 5.0. If you could get your CPU to 4.7-4.8 or someting like that your system should really run close to mine performance with the reverb. It is good. Smooth.

[Xthedarkknight99x]

I'm too tired to speak technical jargon.

 

I'm tech savey but I will not pretend to be any kinda expert.

 

So I will do this.. I will start over and document everything. So that way people can see why I come to this conclusion.

 

thanks for the consideration anyway.. I noticed that when I posted way to much I didnt get much feed back so this is better than nothing for sure.

[Xthedarkknight99x]

Set CPU to 4.8ghz

Turns out memory is 2133mhz.. Will need to replace that "when" I can afford it.

 

Started off with thud's guide as a baseline.

 

The f14 seems to just hate me. As it puts the most pressure on my system. Especially when looking down in the cockpit.

 

Away from the ground things get much better.

 

High frame times are not so bad as I am keeping 45 fps..

 

The indicator seems to be light blue and darker blue.

 

I Primarily fly the f14 so that is what I have been testing in. I fly in a solo map with not much going on and the f16 seem to be so much smoother.

 

 

Ill post images of settings but I did start with Thuds info.

 

These settings arent perfect at all but way better experience than I've had.

Quick question, what kind of cooling do you have for your system? Your temps seem pretty high especially your GPU. Mine hardly ever goes over 60, even running at 99% at certain times.

[speed-of-heat]

OK. Good steps forward.

 

Turn off shadows, leave terrain object shadows at flat. Turnoff civ traffic. And turn off grass, you Never see it, so... It just eats cpu.

 

Finally, and this may hurt a bit in the 14, turn off mirrors, either in game, or in settings.

 

Your memory speed is likely not going to make much difference, just make sure it is running at the speed you have bought.

 

You are currently processor locked, I can't see why, do you have a lot going on in the back ground, browsers open etc?

Pimp is right, considering the level of work you are running your cpu at your temp is high...

[Xthedarkknight99x]

Usually chrome will be open if i am doing anything as I have additional monitors. Usually I have onboard display active. I tested with it on and off and found no difference. In this situation. It was off.

 

 

I have a noctua NH d15 I never considered the Temps high for the following reasons. Tjmax on the cpu isn't being me for thermal throttling to occur. Tj max for this cpu is100c. So as long as she isn't 80, I never worry.

 

I will adjust the cooling so that the fans kick in sooner. I keep them low for noise.

 

Here is the kicker though. The frame time is only like this in dcs.

I tested Assetto Cosra and Project cars 2 and even before I sent my rift s in for repair Il2 ran better. My cpu frame time was sub 6 and was still this way after turning up the settings.

 

So I seem to be having way worse performance in Dcs and the f14.

I may not even worry about it at this point haha. I certainly feel better after seeing the performance in other titles.

DCS is worse than most other games.

Using more or less only one core on the CPU, having a top notch CPU reasly doesnt help that much.

There is talk about the future transfer to a new graphic engine(forgot the name). When(?) this is done we can hope for better performance.

 

The F14 and Viggen( Heatblur) demands more of your system then the F18 and Mirage. Easy to see with the same settings. Harder to get a smooth gaming.

[The_Nephilim]

darknight you say your memory is 2133mhz, was this the speed it said when you bought it.. Can you put on the XMP PRofile for this ram??

 

I would also try to get your OC a little higher to like 5.0ghz..

 

Also you said you run 183% SS that is pretty high and will demand alot form your system in DCS, ok you say you have the reverb what is the native res of that because if your running 183% SS that is probally too high for DCS

[imacken]

There a few things going on here.

Firstly, it is likely that your 2133 is the base speed, and not the XMP profile speed.

Secondly, 183% is OK in SteamVR SS, but I suspect this is a throwback to before the setting changed to be 100% for native on the Reverb in recent updates. What number of pixels are you seeing in SteamVR settings for 183%? What version of SteamVR are you running?

[Xthedarkknight99x]

Just gave it a real fast look.. Set Steam SS to 100 and tested it.

 

Even with pretty low settings in DCS the mirrors just destroy smoothness. Mirrors off seems OK.. but kinda a harsh reality that i have to leave them off. I know this wasnt that way before.

 

Cpu wont hit 5.0ghz As it requires way to much voltage to get there yay for silicon lottery.

 

Memory is reporting 3100mhz in bios with xmp turned on.. wont fus with it anymore. Spent more time trouble shooting this issue than playing with my toys.

 

 

Spent some time dialing in settings for Assetto Corsa and Project cars vr. Havent touched Iracing yet.

 

 

I was able to push around 130 Steam ss with moderate settings before fps would drastically tank. I think i'm happy with that.

 

Overall I appreciate the help but i'm done fighting with it. I spend 40 hours plus a week working and trouble shooting this thing is starting to feel like a job all over again.

[URFIR3D]

Hey @Xthedarkknight99x did you ever find a way to make it run better, I'm also on a 8700k at 4.7 and having the same problems you were.
