Hi,

 

I have basically everything running at max settings. GPU is a GTX 1070.

 

In single player I get very nice performance, the GPU is running at around 99% and the CPU around 50%. FPS is around 60.

 

In multiplayer however, it appears as if the GPU is not used at all, and never at max performance.

Often, I see 0% usage. 80 at the most. CPU around 20%. FPS is now 0-20...

 

Going back to single player and the GPU usage is back up and FPS around 60 again...

 

I was hoping someone could help me solve this problem...

If this is before you select a role/aircraft either step away for a few minutes or fight the lag and select an aircraft and click briefing/fly.

 

I think it might have something to do with loading in all the available aircraft and their loadouts or something but I can't say for certain.. but anybody I fly with has to go through this routine when first connecting to a server. My reason for guessing this in particular is because of the way my system hangs when I browse loadouts in the mission editor. 104th and most of the servers people fly on have a many many aircraft available with lists of premade loadouts in the dropdown menu. Most SP missions you fly won't have near as many planes and various loadouts to deal with.

 

Anyway - back to topic - just give it a few.. or select the first plane you can manage to click in and spawn in it. It should get better. Hoping there's some kind of fix for this in the future but it's not just you if it's prior to selecting an aircraft and letting everything load in.

 

If not maybe turn down shadows and go without MSAA if you aren't already.

Thank you Headwarp for the quick reply.

 

Yes, it is when I want to select an aircraft to fly and for a long time after that as well.

 

I have just once waited long enough to be able to fly and then everything was running fairly ok. All other times I've just Ctrl-Alt-Deleted myself out of DCS thinking everything was stalled...

 

But I understand this is a common bug and then hopefully it will be fixed a beautiful day...

I wait about 3 minutes for everything to catch up once you are actually connnected to the server and looking at the aircraft selection screen. If you have a second monitor you can have task manager opened on the other monitor, open the process tab and you'll see DCS. Disk activity will be there the entire time until the FPS clears up. It is clearly loading things in at the beginning.

 

Some campaigns that simulate an ongoing war that encompasses the entire map slow mine down to crap. 6 FPS on an I7 7700k w/ 16 gigs of ram and 1060 6gb. That's because it's tracking absolutely everything on the battlefield and the mission author put a BUNCH of units all over the place.

 

I would hope there's a way to treat this like a renderer for 3d gfx. It doesn't do anything with the data you don't actually see in front of you, but then how does it track the progress of the rest of the battle?

You need to keep in mind that whenever you load an aircraft for the first time it's shaders get compiled. That can take quite some time. On subsequent missions with this aircraft loading times will be much shorter. This happens around when your progress bar is at 45%-60%. When you see it stuck there, that's when it does exactly that. be patient, use a SSD, have enough memory, that's all you can do.

 

Online, well, yeah, be even MORE patient. I am 47 and I have patience, I do remember my own temperament at 27 and 37..be PATIENT.

Despite I have a very fast ISP, a very fast rig, it takes AGES until I can scroll & select a slot, type "red" in Chat on BF.

Once I can select a slot, it goes really quick, no further delays in getting into the cockpit or such. This seems to have improved. Maybe only my own experience.

 

If you dont have a SSD or too little memory, loading anything is a pain.

 

I have a "test" install on HDD, 2.5beta....you just cannot compare the performance between the 2 installs. SSD vs. HDD day and night.

Same applies to 8GB RAM. You will have to offload right away, exclude the SSD and you get merely stuck in I/O.

 

DCS loads damn slow even on the fastest rigs but you can also do things to help it get it done.

"... use a SSD, have enough memory, that's all you can do."

 

 

This so much.

SSD and more RAM solved most of the DCS Troubles I had on my aged Rig.

While in MP your client has to calculate a lot more stuff than when in SP, it is much harder on the CPU in general (which you can see by the much lower GPU usage, it's waiting) so most of us in MP turn down the things that increases CPU, like view distance, shadows, MSAA.

FPS for me is wayyy down with latest version of 2.5 compared to last version before the buildings disappeared. The textures are much different now too so I think that has a lot to do with it. I never dropped below 45fps before in Vegas with my settings in VR and now I'm dropping to 22 and hovering in the 30-35 range. There are also no ground shadows now with DS turned off. Ugh. I only do SP.
