Why Are My Frame Rates So Low DCS2.1.1?

[gary palmer]

My system specs are as follows:

 

i7-4770CPU @3.4GHz.

16GB Kingston RAM KHX16LC10K216X RAM-with current settings use about 13GB of this RAM within game.

DCS2.1.1 on Samsung 850PRO SSD.

Windows7-64bit on Intel520 SSD.

Run 1xScreen Dell U2713H monitor at 2560*1440 resolution for game, but have a dual monitor setup.

Attached is a screenshot of my System setting within DCS.

Graphic card: ASUS GeForce GTX1060 STRIX OC 6GB GDDR5 using Nvidia driver 378.66 with default setting for 3D Custom settings.

ASUS Z87-C Motherboard, revision 1.02

I never overclock anything as can't be bothered with instability issues that can bring.

*attached is a screenshot of my System settings within DCS2.1.1

 

Am aware that new DCS2.1.1 is a major upgrade from older 2.0.0 and much more resource hungry. On old DCS2.0.0 and 1.5.6 with max settings everything ... no stutter/lags and smooth rendering always.

Am getting frame rates from 19fps upto 56fps within DCS2.1.1, which vary according to where I am flying...if over Los Vegas

close to ground and major buildings of city is about 25fps...(get some stutter/lag), but if high up well off the ground over bare desert

am getting about 56fps...(where is smooth rendering).

 

Maybe there is nothing wrong other than new DCS2.1.1 is a hungry for resources game and maybe in future DCS developers will make game engine more efficient? Is a new order of things.

Am wanting to know if these are reasonable frame rates or can I tweak/improve on them by changing something??

 

Thx...Gary

Turn OFF MSAA and FSXAA if you use the new Deferred Shading option.

Not sure if cranking up preload radius is a good thing for a 6GB VRAM card, universally considered 1080p rather than 1440p performer. Mind You, even on default "high" preset the radius is somewhat lower. But that's something to be more thoroughly tested...

 

MSAA, however, as noted above is a confirmed performance killer, even for stronger cards (with deferred shading, that is)

 

This weekend I was checking out fps differences between in-game MSAA (on the lowest 2x setting) and external SMAA+FXAA injected by Reshade, with my GTX1070. Result - 15-30 fps hit on Nevada alone, ouch! Plus, more cockpit lighting issues. Didn't even bother testing poorly optimized Normandy, or higher settings for that matter - I'll stick with Reshade, even though AA quality is lower.

forget 1.5.6 you can not compare the settings from there as 2.1 is a different beast now.

 

my advice as you are running a higher resolution

 

visibility range - dont use extreme go lower

res of cockpit pit - dont use every frame

MSAA - for now use x2 or off ED have some issues with MSAA currently

anistropic filtering - x8 or lower

 

I only run 1 screen for DCS at 1080 and get 45 - 100+ frames generally

 

if you want to see frames higher than 60 turn vsync off

[gary palmer]

Thx BitMaster...turned off MSAA within game System Options and yep frame rates now at 42-65fps and much less stutter. Funny thing is if I set MSAA to 2x the mirrors in M2000C remain with a frozen image (static); and if I set MSAA to 4x or higher they work as normal as is also the case with MSAA Off as u suggested. Turning MSAA Off does produce a sort of shimmering effect on building structure around Los Vegas but is a minor matter.

 

Regarding the FSXAA setting I cannot find this in game but is a setting at Nvidia Control Panel>3D settings called FXAA which is set 'Use Global Setting (Off)', so is Off already. Is this setting u mentioned as not sure where to find FSXAA?

 

Thanks Gary

Thanks BIGNEWY, Art-J & BitMaster. MSAA Off made big difference with stutter in and around Los Vegas with about 60fps in cockpit and tad higher outside cockpit. VSync Off increased in cockpit fps to about 70fps and outside view fps to about 100fps. Though the GTX card I use was good for max settings with 2.0.0 and 1.5.6 at max everything...also believe using a dedicated Samsung 850 Pro SSD for all versions including 2.1.1 helped considerably.

Unless one has some sort of ultimate system these results are fine by me and am happy with results...Gary

Not all settings turned on via nvidia cpl work in DCS, but you can try using at least FXAA. This one works. It's not perfect - causes some all around blurriness, but reduces jaggies and shimmering a little, while not impacting the performance all that much. Matter of personal preferences.

FXAA is Shader Based Anti-aliasing, Less Performance impact, You can use FXAA w/ Shader Injectors like SweetFX etc.. but It's not recommended to install a bunch of Mods into 2.1 at the moment.

 

AS for the M2000C Mirror Issue, will look and see if it's been reported if not try and re-produce to report on my end.

[gary palmer]

Thanks SkateZilla...regarding M2000C mirror issue:

QUOTE>Funny thing is if I set MSAA to 2x the mirrors in M2000C remain with a frozen image (static); and if I set MSAA to 4x or higher they work as normal as is also the case with MSAA Off<UNQUOTE.

 

Some additional info about the M2000C mirror issue is that toggling SHIFT+M which I think is suppose to show or not show mirrors also results in mirror being frozen-static or not frozen. Seems like a bug so thought I would let you know. On one occassion the mirrors completely disappeared-which could be mirrors toggling Off but was not done/actioned by me using SHIFT+M.

 

Thx Art-J about FXAA is an improvement being On; and definitely almost completely removes shimmer and jaggys as you mentioned. For me it does not seem to make much difference in blurriness but am running 2560x1440res.

Changes which I have made so far are MSAA-OFF, VSync-OFF, FXAA-ON and is a big improvement in frame rate and overall smoothness.

I must say that I don't know if it's AMD or Nvidia's issue is why SLI or's crossfire is not supported in DCS but it becomes an issue when you have a system or you could get cheap cards put them together and have a great system and yet it doesn't support in DCS. this also comes about when we're on the verge of Intel's icore9. it'll support 16x pci express..!!!!! I think even some of the I seven is coming out will have this . Either way it would make a big difference in this single core running game of hours here that I sorely love but become increasingly frustrated with

this is what i do at 1440p gary

Take a look here. Made a significant improvement in my performance.
