DCS framrate tips and info

Hi all

 

could anyone give me some tips or optimization to improve my FPS in DCS 2.1 please, experiencing some slow rates

 

 

I have a i7 950 running at 3.07, GTX 980 ti 6gb OC , 12gb ram although I have another stick that I can add for 16gb

 

Are these specs above good enough to play the game fairly smooth? my GPU seems pretty solid to me?

 

A little frustrated at what I can tweak to improve the FPS a bit more

 

thanks

 

Gazmon

and your graphics setting are ... ?

 

in the GUI games

and

in your Nvidia CONTROL PANEL

in game AA and AF = OFF, force them in the Nvidia panel.

Turn visibility range to medium, and preload radius to 1/3rd of the slider.

 

These don't hamper with how the game looks, so you can still enjoy the graphics. If it's not enough and you are willing to sacrifice:

 

Terrain textures to low (not much difference)

 

then:

 

lower the shadows/ textures (I didn't go this far)

There is one compromise to have antialiasing turned on and wouldn't eat so much performance.

Internal MSAA 2x looks jagged but if you turn on MFAA in the NCP you get MSAA 4x without any loss of performance.

If even this is not enough for playable frames it is necessary to MSAA in the game completely shut down and the NCP to activate the pseudo FXAA antialiasing.

 

No other AA settings in the Defferred Shading is not possible to apply!

The weak link of your PC is the cpu, which is pretty old for current standards, so in this case I suggest turning off the civilian traffic .. it should help to improve the frame rate (along with reducing the visibility range).

Ok I turned off civ traffic and I lowered vis to medium turned off AA and AF and seen definate improvement

 

What does the preload radius effect , what about high vis and lower preload? Will this still give me improvement with out to much loss in graphics

If you want the buildings and trees to be drawn further away increase the Visibility.

If you want some stutters then decrease the preload radius.

Decreasing preload radius increases stutters??

 

Or is that the other way round?

You should be safe in that regard, looking at the amount of RAM you have.

Is there a reason why DCS 1.5 Bear trap mission is stuttering worse than red flag DCS 2.0 , considering there should be less demand visually

 

Any thoughts as this just seems crazy

Both versions aren't great at utilizing modern CPUs, but 1.5.7 has always been noticeably crappy at utilizing modern GPUs too :D. Then, there's also that recent 1.5.7 bug with multiple ground units generating abnormal fps hit for some reason, probably still unresolved in today's update. Simply put - everything "normal" as per DCS standards ;). Maybe that's why.

.... simply does not work! And in VR it`s so important to get some AA. Settings in NCP seem not to register and have no effect in game what so ever.

After some tweaking I think this is a CPU issue , the faster the cpu the smother it gets

 

It's defo a CPU issue the stuttering

It works :) well, what's your graphics card?

I agree .. I have a processor of similar vintage (2010-2011) and its barely able to run DCS at 60 fps on simple missions .. those with lots of AI units run at 20-30 fps :( ... my next upgrade will be a new processor, most likely a Ryzen 1700

 

Best regards.

Any stuttering is cpu related , defiantly not software issue, I have a solid system apart from an older cpu, stuttering solved

Should I be suffering stutters? Here's some of my dxdiag, and I get some stutters, especially in multiplayer.

DCS is not CPU optimised which is a shame and such a long drawn out issue as we all know, so many users suffering game stutter.. some of these system are high end.. CPU optimisation need immediate address

Exactly. Proper multi-core support would resolve quite a lot of issues people have. DX12 / Vulkan support would help quite a bit as well.

Flight simulators are a genre that would benefit tremendously of both, because of the enormous amount of draw calls.

Yes spot on , this should be a priority system area to be looked at by the devs , upgrades are the answer in the short term but we could get helped along a bit without that maybe

 

But probly won't , back to battlefield lol

Just my $800+ worth I can add. I recently gave my Nephew my 980ti and treated myself to a 1080ti. Running win 10/ssd/4.5+. I saw NO difference in either P3D with every addon on worth having or DCS. Yes, I can run 4k on my 38 inch tv but both sims require you to still tweak. After 3 wks of tweaking DCS, I settled back from 4k to 1080p with 2x spare grid super and most the known performance offenders off. TrackIR/vert sync/ Smooth and incredible looking but add AI battles and DCS behaves the way it always has and probably always will.

Now with GTA, driving sims and other games I can run everything maxed out 4k on a 38 inch tv. So stop beating yourselves up. Its the flight sims which have always been a pita and system killers since I flew Microprose F-19 on a mighty 20 ghz Tandy system.

 

Find a middle ground that allows smooth flight which is CRITICAL but also easy on the eyes with no blaring jaggies. Then stop visiting the graphics settings page and unbind key commands to the fps/performance readout and FLY.

One more disappointed customer, recently upgraded my computer, I fitted a ryzen 1600, GTX 980 ti, 16GB of ram currently running at 2800mhz but unfortunately I deal with stutters. Running the latest build of version 2.1, with the latest gpu and chipset drivers.
