DCS Performance Optimizations?

[KLR Rico]

I already have a couple thousand dollars in hardware that is used for DCS almost exclusively. I'd pay stupid amounts of money to have a new engine that could take advantage of it.

[AtaliaA1]

Paying more is appreciated sentiment to the Developers I am sure.

 

Our genre doesn't allow such unabashed offerings, as we are a very small

part of a very large and lucrative industry. If we were at the same level of

participation as the top rated gaming software out there this would be a

logical and intelligent business decision easily made by the "Powers that be".

Unfortunately this is in our case impossible. Unless we some how get the

ear of a philanthropist. One willing to take on this metamorphic change

you and I can for now only dream of.

They need to rebuild the sim on a capable engine &

Call it "DCS evolved" and charge us for it, I'd happily pay to get rid of these prehistoric type problems

 

I think DCS is an amazing sim but I'm not buying content until it runs well & I can use it without issue

I do run the latest high spec PC ( gtx1080 watercooled overclocked etc )

 

2016 is here along with the onset of VR

 

ED are working toward it.

 

EDGE and getting rid of the seperate .exe's were a big chunk of ED decoupling systems from the older engine for 1.5/2.0.

[adrianstealth]

what is "edge"

 

is not on edge now? is some thing about to change?

 

this month or one of these things that is always coming ?

I doubt that ED is working toward a true preemptive multithreaded simulation engine at this time and this for two reasons:

 

1. The engine has a large lua component in it. Lua by default does not support preemptive multitasking. That being said, I am sure dcs had some form of multitasking implemented by the design through sub-systems.

 

2. Even without lua, the complexity to change a one core designed engine into a true preemptive multithreaded engine, is a daunting task. But I think it could be done. If the shared memory between the thread's processing could be kept to the minimum, and if there are handy sync-points (semaphores) placed within the logic, I think it could be achieved that at least the calculations of the different objects within the simulation could be in separate threads...

 

 

 

The improvement that edge brought is a complete separation from the graphics calculations in a gpu and the calculation of the simulation in the CPU. In the old engine, before 1.5.0, the simulation object vectors and 3d objects were calculate by the cpu, the gpu was merely adding the graphics layer on top of that.

Can anyone offer me some Graphics settings advise based on my system specs below? Attached is a screen shot of my current settings. Thanks,

[bouncerj21]

Hi Fakum

I have a very similar setup except the CPU and have found that this works well for me

 

Hope it helps

 

Thanks

[Fakum]

Thank you

Is flat terrain shadows something you want on or off for better fps?

[Art-J]

^ On.

[JazonXD]

From what i've find, CPU is the only thing limiting performance in DCS. I can set the AA to 16x and yet the performance either doesn't move or barely does.

 

Also, when I get down to the deck or look at the ground war, my frame rates drop to single digits, however, if I force DSR and run 1440p instead of normal 1080p (DSR is very broken in DCS as of now, you have to set your DESKTOP resolution to 1440p and then set DCS resolution to 1440p for it to work properly) I'd get much more stable frame rates even when I'm down low on the deck. If ED actually fixed DSR or fixed it enough that it's convenient so that I don't have to change my desktop resolution every time, I would rather play 1440p on a 1080p monitor.

[kestrel79]

^ On.

 

Thanks that's what I thought, wasn't sure. I'll keep it on.

computer upgrade for DCS

 

i love using the oculus rift for dcs, but my current computer is rubbish, im about to upgrade and start buying the parts, i was going to go for the i5 6600k and a gtx msi 1070 with the msi z170 gaming 5.

 

is it worth me stretching and going for the i7 6700k is the difference in game play worth it? i have the dk2 and will probably save for a cv1 towards xmas or early next year

[aairon]

Thanks that's what I thought, wasn't sure. I'll keep it on.

Intel i5 2500k @ 3.3ghz // Asus P8P67 mobo // 16GB G.Skill RAM // ATi 7950 3GB // 27" monitor // VKB Black Mamba Mk.III // x-52 pro throttle // CH Pedals // W7

 

I hope you're overclocking that Intel i5 2500k to at least 4.3 Ghz that would be a big improvement.

[MikeMikeJuliet]

For all intents and purposes it seems that clockspeed is the one you want to be as high as possible. DCS uses only 2 cores (1 for the game, 1 for the audio), so getting more cores helps only if you have other programs running parallel (so they don't share the core DCS desperately needs).

 

High end i5 should do the trick.

heat blur low is an unnaturally overdone effect

heat blur high is how it really looks

[Fakum]

Thank you Sir,,,,

My honest opinion after going round and round in the forums and elsewhere about the poor performance of DCS is that they have no intention of ever fixing this or evolving it to work correctly with VR because of what some have written here, that it would be too much work and would result in having to start over from scratch almost on the engine.

 

Because of this, I believe truly that they don't care much about optimizing for higher FPS or care about these complaints and they are just trying to squeeze as much money out of this current engine as possible before one day being forced to start over or call it quits.

Bluelight, 2.5 will be a pretty significant engine update, perhaps see what revisions are improvements are made with that iteration. I wouldn't imagine it will do much for VR, for the reasons stated, but I could be wrong. There are a lot of visual features coming, as well as the T4 map tech. Right now, Caucasus performance is very different to Nevada, because of the difference in map tech. This will change in 2.5

that is a little bit of reassurance; it's great seeing the beautiful artwork put into 2.5 and the caucasus map but my concern is the performance and how much it will suffer seeing the textures and qualities are even higher.

[msalama]

Well, my general DCS performance is pretty good. Now there've been patches / upgrades that have caused it to tank every now and then, surely - but all in all, I pretty much get 60FPS solid and no stutters to mention of regardless of where I fly.

 

The reason for this is that I built / configured this (now admittedly ageing) computer with nothing but DCS in mind. How it was done is too long a story to tell / explain here, so maybe I'll do it in a separate thread later on; but suffice it to say, that even this old tincan with an i7-2600K still runs v1.5xxx pretty well.

 

The trick, as far as I can tell, is to 1) disable all BIOS and OS settings that hamper performance and 2) disable absolutely all services that aren't necessary and 3) optimize all DCS settings, including those that are hidden in the LUAs, for an adequate balance between performance and eye candy.

 

Hey, if I can do it, you can too!

 

PS. I don't have VR & am only running a single-display system. So there's that, admittedly.

Bluelight your "honest opinion" means exactly squat unless you're a flight simulator coding expert and know how to do it better. If you can do it better do it. Otherwise...be patient like everyone else.

 

I've watched this game mature more in the last 3 years than many other games mature during their entire lives. Fixing problems properly takes time. Catching up with new tech takes time. I'm gonna let you in on a little secret...some people don't care about VR. In fact, Id be willing to bet if you do a little checking you're gonna find you are a very small minority of the people currently flying DCS.

 

Sorry simple fact. Now, Does that mean YOUR wishes or desires are less important than ours? No. Does it mean your wishes and are more important than ours? No. But it sure he'll doesn't give you the right to come in here and imply the people working on this sim don't care just because they don't appear to be addressing the specific wishes of a particular group within the community. That's arrogant and childish. :doh:

[kestrel79]

I am not. Has always been at stock speeds, but I think I will try to overclock for the first time this fall, as well as getting a SSD and maybe a new video card.

 

Have been thinking about watercooling in order to overclock, but I'd need a larger case to mount the radiator.

#1. You're obviously a fan boy so responding to you is probably a waste of time but I'll give it 1 go.

 

#2. MANY people in this forum share my opinion of not only the poor performance with VR but in the 2D game as well. The difference is it doesn't effect the 2D version as much as VR but based on the numbers and tests, the engine performs worst than any other game I have seen in utilizing GPU and CPU power and there is really no excuse to have such poor performance in such an expensive product. Oh and by the way, they wouldn't have added VR to the game if they didn't care about it.

 

#3. I have a long history in the forums of talking about these issues and providing LOADS of evidence.. begging for the devs and testers (who I know for a fact have seen my posts) to respond and explain these things but the same result always happens. They ignore the threads completely (even though they saw it.. I have evidence of that but wont get into it cause they told me not to.) If they don't ignore completely, then they give a quick generic response that does not apply to the situation at all and is not a fix for the problem. I have also talked with people in the forums who got generic responses when submitting tickets that don't fix the problem. All of these reasons and more, formed my opinion.

 

#4. I am a paying customer, having bought several modules for this game. That gives me every right to say what I am saying. Not only for that reason, but because of my experiences and the people who have shared their experiences with me that are the same. Just cause your experience differs doesn't mean you need to create a post that has no purpose other than to attack me.

 

#5. I am a graphics expert and professional visual FX artist so yes, I know a thing or two about graphical optimization in not only games, but film and have the experience to back it up.

 

Having said all of that, I have a right to my opinion and my opinion is based on evidence as well as my experiences and many others who I have talked with here.

 

Your opinion is based on nothing more than your own experience and using that, you want to call others who you know nothing about, arrogant. LOL :lol:

 

I'd say the only real arrogant person is one who jumps into a conversation that he hasn't followed fully, with someone he knows nothing about, halfcocked, and tries (and fails) to make him feel bad for his opinion. Thats about all I have to say to you.

 

Now lets get back to trying to solve the problems here.

[JazonXD]

This actually helped me quite a bit.

Couldn't think why my i7@4.5 and gtx 980 were stuttering noticeably.

Changed NCP and turned off vsync-now I get 200-ish buttery smooth fps in 1.5.3

Thanks all!

 

I know that I don't have V-sync on but what other setting did you change in NCP?
