help for a newbie with FPS

[Azdack]

Hello. I'm a newbie in DCS. I built my first simple single missions with warbirds (spitfire) and flown them with much pleasure but after a few minutes I had an awful lag flying the mission for several seconds. Then the fluidity came normal again but the lag came back again too. I have a Nvidia Geforce 3070 and a i9 CPU 3.6GHz. DCS is on my SSD samsung 970EVO Plus 2TB with 1.29 To free. Checking task manager I could notice that DCS is using all CPU available.

That lag is quite strong making the game unplayable. I tried to reduce system settings into the game but lag keeps going on. Any help? Thanks in advance for answer.

Make sure your DCS copy is on a fast drive ( preferably SSD ).  Check.  Now, make sure your pagefile (virtual memory ) is also on your FASTEST drive.  Critical if you don't have much RAM memory.  My pagefile is on my C Drive SSD, which is my fastest drive.

 

Really sounds like a virtual memory issue bottlenecking DCS.

 

If that doesn't work, start lowering your graphics settings.  DCS is still pretty CPU bound, and still not multicore capable.

 

I have a 7 year old computer and play on all low.  Get 30 - 100 fps.

@AzdackIf what 3WA suggests doesn't fix your issue, please attach your dcs.log file ( C:\Users\username\Saved Games\DCS...\Logs\dcs.log ).

@3WA : thanks for your answer. Well I have one single SSD and then both DCS and pagefile are on that SSD. Then into the game I configure the graphic settings to medium. With my RTX 3070 the game's stil nice to play. I made two single missions with no object neither vechicles or AAA on the ground and kept the planes Ai flying with orders "orbit" and "engage" - simple dogfight - in that way my FPS are good around 80/140. I will add some ground units to see until where the FPS are good before falling down from 120/130 to 10/20 sometimes 7/8. In single dogfight the game is playable.

@Flappie. Thanks for your answer too. Joint the files you asked. I you can help...thanks.

Thank you for the logs. Please try to fly a Su-25T instant action mission over Caucasus. Activate autopilot (H) if you don't want to pilot the jet and let DCS do its thing. Do you sttill have stutters?

[Azdack]

I’m really a newbie! Icould configure my commands for the spit but Su-25t is bloked, keyboard and everything...i have to find out how to unblock the commands for Su-25t before flying that plane automitacally to see if there are stutters...

I'm currently recording a long track so you won't have to mess with controls to test DCS stability. Standby.

Here you go. Download the attached track below, place it into "C:\Users\userame\Saved Games\DCS...\Tracks", launch the game, click "Replay", then load my track. See if you're getting stutters.

Hi Flappie thanks. Last news : I've built a mission with 18 Ai planes Spits and 109 only two AAA on the ground, settings medium and I had....no stutters.

Regarding the Su-25..there is a folder in user/gameplaid/DCS/input/Su-25...called TrackIr with a TrakIr file. If I put that file out of the folder...TracKir with Su-25 works. By the way the same folder for Spit is empty too..

Now my probleme is to set the automatic flight or automatic pilot in Su-25. My keyboards kee don't work...impossible to make the Su-25 flyable alone...I've seen a tuto for automatic pilot but not simple for a player as me who doesn't know anything to jets...

Thanks

Don't you bother with the Su-25T controls, just download and replay the track I've attached above.

I've sent your my Discord id in a private message. Feel free to call.
