Jerk in DCS

[Matias Oliva]

Playing DCS every once in a while gives me fps jerks, the gpu drops from 98% to 0% and then goes up again. The incredible thing is that I lowered the settings to the minimum and it produced more jerks and the frame rate worsened.

Does anyone know what can I do? I have limited the frames to 30fps to improve the framerate but it is still not good.:helpsmilie:

My laptop: (its new)

Nvidia gtx 1650 4GB GDDR5 128-bit

9° Intel® Core™ i7-9750H (12M Cache, 2.6 GHz)

16gb ram

I use HDD

 

(I check the temperatures and is normal).

 

Pd: Srry for my grammar, i need to improve English! :)

Hi

HDD is not good -> think about SSD with good performance (not the first price)

 

Go i think GTX 1650 is not very good too :-)

Yeah, i am thinking to change to ssd. In DCS its a huge difference?

[Kervinou]

i think so ! :)

[RedeyeStorm]

In DCS you never know for sure what the problem is. I suspect only helps with loading speed and not so much during play. Fly from HD now used SSD before never noticed a difference during play.

I suffer the same issue and have DCS installed on a (rather fast) SSD. By my experience SSD does not help with ingame performance, only with loading speed. Also the GTX 1650 isn't the best GFX card to play DCS, yes, but this is for sure not the reason why his GPU usage drops to 0% and then goes up again.

 

I suffer this in SP after playing for like an hour or two, in MP a bit faster (or immediatly after beeing shot down). My FPS is at stable 60-65 in MP and then drops to 1 with my GPU usage dropping to 0% in tandem. Then it goes back to normal, just to drop again after like 10-20 seconds. The sim turns unplayable and however only rebooting my pc helps for me.

GPU going up and down ... Laptop ... This may be power saving, throttling due to exceeding temps.

thank man, i will check that!!

I'm having the same issue and I am running on a new pretty fast machine. I've been posting about them on an earlier thread called, "Studder Non Stop on new Machine". I thought it had to do with Track IR, but now I am convinced it's may not be the problem. Try loading DCS without Track IR and see if the Jerks go away. On my machine I see them about every second or so and I see the framerate drop out. Not sure what's causing them since I am new to DCS.

Thanks for comment! :lol:

Yes, I am also new, but I searched a lot and found a video that helped me a lot. I will post the link and hope it helps you too.

This increased my performance, but did not completely eliminate the jerks, it only reduced them as much as possible. I think DCS is the problem, not our computer.

Good luck!

If you cant see the video, here it´s the link:

Edit: i dont use track ir

TRY this

 

delete the fxo and metashaders2 files(saved games folder)...then defrag the entire DCS installation folder.

You do not defrag SSD's!!!

In his first post he says he uses an HDD

[prccowboy]

I had similar issues in the past. increasing my virtual memory (fixed size) and moving virtual memory to a SSD helped (make sure windows is NOT using any HDD's for virtual memory - even though you set virtual memory for a SSD, windows may also be using other drives. so you will want to check drive by drive whether windows is using it for virtual memory)

 

edit: DCS (and other windows background activities) will exceed your 16GB in memory commits, so Windows will start storing memory on your HDD's = instant judder/jerkiness in game. So, make sure windows virtual memory isn't using slow HDD for storage

are you Using the new windows 10 hardware accelerated GPU Scheduling?

 

If so turn it off and test.

Yep, i use HHD and i already defrag them. Thx for the comment! :)

Trying to fix the Jerks, i increase my virtual memory in my HDD because i have the game there (and help me alot) but you say that it's better to change that to the SSD even if i don't have the game there?

Nop, i dont use that. But I realized something. When I started a very heavy mission, it produced too many jerks, but when I restarted it several times and went through the same place, these jerks decreased more and more. It gives me the impression that the load of the objects was the problem (maybe my hhd its very slow and the jerks its due to that?).

Hope I explain it well, hahaha

yes, the virtual memory is what windows uses to hold stuff that doesn't fit in RAM. So, use the fastest storage you have if you want jerk free

Ok, thanks for the help! :)

its your hard drive . that speed is no good for dcs , you need to run 7000 rpm . i bought a 2tb 5400 and put into my desktop and i have stutters and stutters the hard drive is playing catch up . i installed on a 2tb 7000rpm and no problems .

Delete these folder?

[Lange_666]

@Kevo320: You can delete them, they are newly created when you run DCS again for the first time after you deleted them.
