Patch notes discussion 10th March - 12th April 2023

[Gunfreak]

So I see this in the patch notes

• Rare occasion of stretched cockpit resolution happens randomly on first simulation launch

 

I haven't gotten it while playing, but I now see my OBS recording is stretched...

I have "auto" overclocked i9 9900k from 3.2 too 4.8-5.0. Should I declock it back to 3.2?

No of course not, my discussion was on using hyper threading or not, nothing to do with overclocking. Historically flight sims were not known for making any use of hyper threading so it was common practice to disable that in the PC Bios. This new Multi Threading by DCS changes that line of thinking now. You want more threads to make better use of hyper threading, at least up to 32 threads at which point DCS does not recommend more.

People having big gains in fps and some guys still blaming ED… Ridiculous

[Tango3B]

Good patch. Thx ED. On my end the increased performance is very very noticeable. For me it feels like a completely different (way better!) sim. So, the first iteration of MT looks very promising to me. Looking forward to an even brighter future...

I've always had hyper threading on(none of the DCS VR optimisation guides I've read mentioned hyper threading,  so it's been on by default since I bought the motherboard.

On my rig so far it's been a massive success. Good job ED! Bravo! Bis! Bis!

Inaccurate. It says more than 32 threads

Now it does yes, but I'm pretty sure it said "32 threads" when I read it, which was only a few minutes after it was made visible. It must have been edited after.
I commented on what I read, which was correct at the time.

In any case, it doesn't matter really.

[Sr.]

Should it matter that only 6.3GB of 16GB VRAM is being utilized? As reported by OXRToolkit.

Great update ED and congratulations on rolling out the first beta with M/T, the shadows fix is very welcome indeed along with all the other bug fixes.


DCS Shortcut used for clarity
"D:\DCS World OpenBeta\bin-mt\DCS.exe" --force_enable_VR

Regarding M/T I saw no improvement, same FPS in all my test missions, HT is enabled in my BIOS, disabling it makes no difference

Instant action/Syria/F18 - Free flight
Instant action/Caucus/Apache- Ready on the range

G2 with 4090 64gb 3500 DDR4, 13700K

All my settings the same prior to the update, both missions sit at 55-60 FPS which is the same as post patch
Enabling the shadows I now lose only 1-2 FPS, but the game looks heaps better.

DCS FPS counter says im CPU bound.

Hello everyone, ask, you have to make some change in reshade to use it with beta m / t, if you can help me, thanks

[wilbur81]

Great stuff for me on the MT end after some quick tests: With all my same (mostly high or maxed out) settings in 4K, I'm seeing solid 60 FPS in heavy test missions, busy Supercarrier ops, etc. when I was previously dropping into the low 40s. Great step forward! Well done, ED Team.

Good to hear, and enjoy. 

 

[MarkyMark]

This is good. Very good. Well done ED.

@NineLine
is there a dedicated Forum thread for MT reporting, I saw you mention reporting bugs to a dedicated forum post but you never linked it

Make sure you report MT bugs in the dedicated MT bugs topic, it will get lost in here. Thanks

 

[Beirut]

This is delicious. I'm seeing a good ~10% even in solo flights. Ran a flight over Dubai with the settings a bit high and got ~29 to 30, hit the MT and got ~34 to 35. That's nothing to sneeze at. Going to play with this more tonight. And is it my imagination or this helps the FPS with the "Kaboom!" and subsequent fires you see on the MFD? It seemed like I took less of a hit specifically when zoomed in on the screen.

 

Credit where credit is due, and ED gets it.

Regardless, 10-15fps is still a considerable gain! What were you expecting? It's been said right from the onset that you should keep your expectations reasonable. MT should improve slightly over time, but then there is also Vulkan and DLSS coming in the future which will bring further improvements.

This was an excellent release/implementation from ED. I'm sorry you had your expectations set too high. 

I did not get 10/15 fps with my system. I only got around +5 fps in vr with rtx 4090. So yeah, i was expecting more. With MT i only got back in terms of performance what i lost with shadows update for 2.8 update. 

[EbonySeraphim]

Amazing job with this. It's not perfect (I'm getting UI issues), but they are minor and I'll try to have detailed reports if I don't see that they already exist.

 

I'm a software engineer, ex hobby gamedev, and would LOVE LOVE LOVE to see a detailed blog or interview with the development team about the challenges, surprises, and overall development process of bringing multithreading to DCS. Players would love it; I would love as it as an engineer; and the rest of the game dev community will want to listen in on how a "game" improved performance by this much for just about all PC hardware. Though DCS isn't super well known to gamers at large, I get the feeling that news of this level of improvement will cause ripples in the general gaming community as well. Companies like EA/DICE will be wondering why suddenly players are expecting Battlefield to better exploit their 16+ core rigs for better performance. Most games do not have demanding simulation/computation needs and the devs know it, but there will be curiosity if they do something better and achieve even a fraction of the performance boost.

That's the same as me

If any of the tech wizards out there can isolate which settings are specifically helped with this, that would be lovely. Thank you.

Yep. And still have fps drops if i look to an area with multiple ai units. So still have to cap fps at 55 in xr toolkit 

[312_JS]

Massive performance increase with the MT. Thanks a lot team!

[Cooler07]

Major improvement with bin-MT from 45-50 fps to 90-100fps

 

75fps in AH-64 with rain caucus map

 

System= 

i9900ks 5g

64 ddr4 3800 Corsair dominator

Asus ROG 4090 

Pimax 8kx normal FOV PD 1.5

OpenXR for Pimax 

(((((NOTE)))))) NOT running command line -forceXR -forceVR

 

Again not running the command line setting

 

DCS PD .5 

Max setting on all but clouds and shadows are flat with blur.

 

I will say I had just installed the 4090 on 3/9 and the FPS was 45 to 55 with lower game settings.

 

Also I don’t think it made any difference without the command line because I’ve been running game like that for a few weeks.

 

I’m seeing 75% increase load on ALL 8 cores and 16 threads.

Also see 25% use of VRAM and GPU AND 60 to 70% increase.

 

Have to say EXCELLENT JOB ED

[PLUTON]

Hello everyone
how can i know if my TM is activated or not?
and how to?
Thanks for the help

[Tango3B]

One more thing from me for those people experiencing problems with MT, currently. Most modern CPUs have HT enabled in BIOS but please make sure you also check some specific settings in msconfig. Go to msconfig, search for "start" and then go to "advanced options" and look for processor count. In this very menu please make sure you set ALL(!) of your available processor cores if you haven´t already done so. My processor count was initially set to 1 instead of 20 cores so you get what I am talking about here, probably. This made the difference for me and I hope it might also be helpful for some of you guys, too. If you do not konw how many processors (cores) you have, do not worry. The maximum number is shown in "advanced options" under processor counts. Just select the maximum number and you are good to go. I hope, this helps.

What it should look like is this, with the "Number of processors" unchecked. That way Windows manages the cores and all of them are used. This function is really available for those who want to limit how many cores are used.
