Low GPU and CPU usage but LOW FPS also...why?

[Corrigan]

Okay, so I started your mission and I do get kinda low fps too. Not 20 fps though. Looking straight ahead at mission start, while paused, I get 60 fps with mirrors off and 38 fps with mirrors on. I see fps as low as 30 if I fly for a while after mission start. My settings are attached.

 

I think it's something strange there, along the coast between Sochi-Adler and Gudauta. Moving a free-look camera there drops fps from 150 to 40 quite drastically. Maybe a model that has too many polygons or something? ED need to take a look.

[msalama]

Just an aside, but to me, the Eastern Black Sea coastal area has always been a problem performancewise, almost as if there were something fundamentally wrong with the scenery model or something. Can't really say what it is exactly, but I've a hunch that since the area is quite heavily urbanized, it's the amount of districts and/or houses that is causing this. Just a hunch, though.

[Corrigan]

But we shouldn't be getting the same performance as in central Las Vegas. There's something wrong there.

[msalama]

There's something wrong there.

 

No, that's precisely what I mean, there IS something wrong with the area. And I'll even be so bold as to claim that it's the massive amount of poorly optimized buildings / districts there. Just my €0.0002 / $0.000333310247 though ;)

[G00dnight]

Going back to the settings try turning aero back on. And test.

[Ala12Rv-watermanpc]

You're doubling up on MSAA, Anisotropic with the game egines implementations.

 

Restore Nvidia 3D settings.., set maximum performance, and test again. Leave all other settings default.

 

Sorry mate but I dont understand why Im doubling MSAA?? , Im setting it only in game:huh:...AF maybe (dont think this is the problem as I tried just setting it in one place and performance was the same anyway)

 

Looking at your screenshots, it appears you are in the area of Gudauta/Sukhumi? Do you have this low FPS problem elsewhere? I have noticed since 1.5 that in the Sukhumi area, my framerate also falls off the bottom end of the scale.

 

Yes man, Im exactly in that zone...performance is not that bad in other places, in fact, I can push 60fps most of the time in other places BUT as I installed the game a few weeks ago Im very new to DCS and cant talk too much if performance is better or not along the map...

Thanks for your help mate!!:thumbup:

 

Well, I see you have Civ traffic at medium while I have it at high so that shoul decrease fps a bit...also, remember I have "fardistance" in .lua at 40.000 from 30 or 33.000 which is the default value if I remember well +the texture mod...you have disabled lens effect too, and dont know whats your gpu OC...mine is 1535/3700. Btw, I also increased preload radious to 220.000 as you can see in options (dont see any improvements anyway).

you are right, there is something wrong and "old" in the way the game engine works and thats something that really worries me after EDGE is suposed to fix all this things...well, it looks bad righ now for EDGE :cry:

 

Going back to the settings try turning aero back on. And test.

 

Well, despite I have this turned on the truth is that it doesnt work actually so I tried disabling it but same performance...also I must say that very frecuently I get the windows message telling me that Im low in performance and if I want to change to performance mode in window even when I barely see 7Gb of ram used out of 16...why am I getting this message???:huh:

 

 

Anyway guys, I think we are loosing the point here, I mean, the problem is not the performance by itself but the LOW GPU/CPU USAGE!!!!!!!!...it doesnt matter how we have the settings as soon as game drops to 30fps leaving 70% of the GPU available totaly wasted!!!!..THATS THE PROBLEM HERE!!!...and more when flying in a "empty" place makes the gpu load rise to 60%...so why in hell would it go to 30% when in fact we really need more POWER?¿?¿?¿?...there is something wrong here and Im also thinking about Nvidia drivers, because maybe with the new engine some changes must be done at driver level in order to achieve good hardware management...

Leave your Nvidia control panel settings as application controlled, and adjust MSAA and Anisotropic filtering in game.

 

If you don't have improved FPS from there something else would be wrong. You should let the game apply the graphics settings, not force override from Nvidia control settings. Only after you see what your max FPS is with drivers settings default, then start adjusting where you see fit and measure the difference to what you prefer to use and how it impacts your FPS and visual preference.

 

Sure try an earlier driver version.

 

Just from observation. I've noticed in my situation VRAM OVER 4GB easily being used with very high in game settings.

 

Maybe... Memory management still needs be optimised in the alpha,beta updates and this is adversely affecting your card.

 

The 970 was Nvidia's bad child.

Well, the GPU usage might have something to do how the GPU is designed. The GPU is made of several clusters that each contain different processing units. And if not the whole power is needed equally let's say tessalation unit only 5% but texture unit 95% we have an average of 50%. Althoug just a wild guess it might explain it.

Ok, I will try what you say mate, and I know about the 3,5gb "cheat" from nvidia, dont worry :smilewink: .I know you tell me to help so dont worri mate!!:thumbup:

You might be right mate, but then something should be done to the way the game engine do things because if a gtx 970 cant run this at max settings then there is a serious problem...

I personally think that whole GTX 970 memory issue was a little overblown.

 

I actually ran DCS Open Alpha 2.0 for a while, with things so maxed out I was using like 3.7gb of vram.

 

Never saw a hiccup or performance degradation.

[Lt_Maverick]

All of this being said, it is a shame dx12 is not being used because it stacks the vram.

Yeah, I dont have 2.0 but people are reporting a lot better performance on it...maybe less villages/objects count??

I wanted to say something else a bit offtopic...its me or this game runs horrible as soon as its below 60fps?¿?¿I mean everytime it goes below 60, even if its 50fps it feels like 10fps...do you feel the same?

 

EDIT: About below 60 fps I mean below whatever vsync frame rate you choose...its also something worthy to say.

I have not noticed that. In fact in the mission I get the very low frame-rates now, 30-35fps at the start, it is still silky smooth for me and stutter free.

 

Strange how so many different folks see such different results...

[Lt_Maverick]

Hi guys, Im really enjoying DCS 1.5 since a few weeks but there is something driving me crazy since the start...with the system in my sign (with vsync activated in NCP as I cant stand tearing) many times for NO REASON I get low fps (below 60fps) with lots of GPU and CPU power remaining :mad:...sometimes I see my fps lowering as low as 40 and GPU at 50% and CPU over 40%...WTH?¿?¿?...Even I cant use mirrors as they COMPLETELY TANKS my fps to unplayable levels.

 

I have tried limiting my fps in both, game configs cfgs and riva tuner through msi AB, using full screen (alt+enter once in game wich greatly improves stuttering but not fps drops), using windowed, using Timer resolution, configuring NCP for vsync, AF, high performance, etc. nothing works.

 

The only thing that bothers me is the vram usage which may be the culprit...when I see in AB the vram usage some times in heavy graphics moments I see a very low vram usage (like 2gb or 3 gb) which could be normal, but the weird thing is that other times in very light conditions I see vram usage skyrocketing to 3,5/3,8Gb Vram so I suspect there is something weird here but even if Im out of vram that should not be the reason for a sustanined low fps and low cpu/gpu usage I think...also, system ram is not that heavy in usage as other report because I have NEVER ever seen anything over 7,8Gb total ram usage out of 16Gb...

 

I must say I have some mod/tweak done in my game which obviously increases system resources usage so if I delete them my system is able to sustain a constant 60fps flow but this cant justify why my fps drops when there are yet resources availables...

 

Btw, the only thing I have done to the game are:

 

-Starway 3.2 texture mod

-Increase objects distance (fardistance) to 40.000

-Increase texture loading (distance10x10 and distanceLevel0 ) to 150.000 each.

 

Im running 1.5.2. Settings in game are all maxed out except the DoF (off) AA at 4x, MFD at 512 single frame and 1080p.

 

Any help here guys??:thumbup:

 

 

I saw somebody mention this somewhere, I can't recall if it was here, but I dropped my tree rendering distance from the max to the min and my FPS doubled.

what are your setting? specially vsync...are you using any fps limiter??do you have any low gpu usage problem??

But again mate, I dont want to lower my settings, I think this is not the way...I have LOTS of computing power wasted in my system so lowering settings is not the problem as soon as GPU usage is at 30% during those moments :cry:...what I want is to see my CPU/GPU usage goin up...

 

Remember guys this is not a "how to make a system used at 100% run smooth by lowering settings"...this is a "how to make a system running at 30% not to go to 30fps no matter the settings"...

[OnlyforDCS]

There is a simple explanation for lower CPU and GPU usage. Bottlenecks. I don't want to delve into the technical explanation but it basically boils down to this: There is a lot of room for improvement in the Alpha Code 2.0

 

Only very efficient applications and programs run at 100% CPU and 100% GPU usage rates at all times. (On effective hardware of course)

 

So basically you need to take a step back, and remember this is Alpha code. Of course it's not optimized! This is the reason why you are not getting 100% efficiency, and this is a good thing! Why is it good? Because it means that there is room for improvement and that the stability and performance of the game should only get better with time and fixes.
