Multithreading is Awesome!

[Rex]

I loaded up a mission that I struggle to get 30fps on, and I was hovering in the 90s with runs to 120 (the max refresh for my monitor and the FPS limit I set).  It's running everything significantly faster.

I have an 8-core/16-thread CPU, and I used to never see more than about 15% CPU utilization MAX during DCS (given that most cores were idle), but now it's using 70% of my CPU, which means I'm maxing out numerous cores.  My 2080Ti finally sees 100% utilization too.

While it helps VR to some extent (I had one VR session glitch down to like 11FPS, but most held 40-80), from my testing, my monitor (5120 x 1440) sees a much larger benefit.

I gotta be honest, ED didn't seemed super-optimistic that MT was going to be a huge deal, so my expectations were fairly low.  I figured they'd throw some damage-model tasks to a couple of other threads, and call it a day.   I figured it would help a little, but not be overwhelming (kind of like when iRacing threaded their damage models).

After a couple hours of use, however, this seems like a game-changer to me.

Really nice job, from what I've seen so far, it finally makes those multi-core gaming CPUs worth the money, and it lets the graphics cards use all of their resources.

So say we all!

I'm not sure what kinda Sugar Plum Fairy...Ziggy Stardust...Cajun Voodoo...Black Magic Rock-n-Roll  You Developers at DCS are Practicing???

      But I Like It!!!!!!

Thank You for this Magnificent feat!!! I can not even imagine how much Rocket Science went into making this happen!!

Same for me, 12-15 FPS increase in VR

So far, an incredible performance gain! FPS when around the super carrier stays at frame rate cap of 143fps most of the time with MT!

I don't have fps counter but things load a lot faster, some artifacts in vr but nothing major. Had some crashes when exiting to desktop. But looks promising.

I need further testing, but on friday i flew a AH64D with my friend in a small mission (Apache always gave me very bad FPS regardless of mission size), and the FPS was very good, like ~90-100 the whole time. Feels very promising, but i need to fly a bit more in bigger MP servers to convince myself.

Try RCtrl+Pause. Counter should appear in upper left of screen.

It even made my 1,500 unit Omaha Beach scenario marginally playable by doubling the framerate!  This is my entire "master" D-Day mission which I always reduce from before actually playing.

Same Game-Master view from the beach for roughly the first 5 minutes of the mission.

Not bad for 300+ Higgins Boats, every WN Strongpoints, Troop Ships, LSTs, Allied Bombing Campaigns, Artillery Batteries, etc.

10700K 3080ti Reverb G1 here.

Went from 39 to 50fps in the SuperCarrier cold&dark mission, 37 to 53 in the FA18 Instant action Battlefield.
Having in mind that this is only the first iteration of MT, future is going to be great !

I just miss SteamVR, for its reprojection which is way, way better than OpenXR's one ( stutter and ghosting ruining the experience ). Hope the hotfix will be available soon.

[jackmckay]

Its finally playable. Just that. Ready for some hard core missions now.

Yes, looks like it, especially for those of us with less than stellar machines.

I must say this is the best improvement yet!! I run the F-18 module and the Super Carrier, and all my stuttering has gone away!!!!!!!!!!!!!!

Good Job guys!! Keep up the good work!! I use the Track IR and lock at 60 FPS and it stays at 60 FPS absolutely not one stutter!! All other settings maxed out!!

I would always have minor stuttering. And I have tried all the fixes but always had that minor stuttering. But not anymore! Not one stutter. I use a RTX 2080 super graphics card.

Have just purchased The Persian gulf (on sale)

Prior to the latest MT update, I had no intention of purchasing this map.

But if DCS are going to potentially save me £600 in a GPU upgrade through some seriously diligent programming then I'd like to support that.

When the ground AI improvements come out (which I hope can be manifested more fully due to the extra bandwidth we now have to play with) I'll buy up any other modules I've not got.

 

Thanks DCS

I am so amazed! my head keeps nodding up and down like a bobble head, i never could put up my settings past medium and the temps were ridicules now after almost two years with my new system and DCS 2.8.3 i turned my settings  on high an ultra and i cant believe it! temps are low and it runs as smooth as butter not sure about FPS i am sure its high and amazing performance ,not only that, i guess ED fixed the AH-64D i  because i could not fly it a month ago so i went back to the KA-50  now without issue or crashing the ah-64 fly's like a dream what can i say amazing !! and i figured a good test is flying ground OPs where the the graphics are pushed to the limit.

i could not get the FPS meter to function on msi after burner and i had to roll back my nvidia driver to 528.49 i was having blank screen issues on my Steam game interface .  There is always something but it wasn't the sim this time its hat off to the ED team great job !!!!
