Bad Performance with Nvidia 3D

[Latorimo]

I am flying with DCS World for some time with NVidia 3D/Shutter for now - with the modules Mi-8 and Bell Uh-1 Huey -

 

for 3 month or so the performance is getting low, worse and bad. Although I have a framerate of 30+ (fraps) I get tons of microstutters - it stutters that much that the "framerate" tends to be (to seem) 10-15 fps.

I `ve tried some things with less than more sucess. First, i leveled down the video settings in the nv control panel, as seen in a post arround here. Then I made the sensitiveness of the axe control p&r looking like a quadratic equation/function with a factor of 30 - that helped a bit - I don`t know why exactly by the way. The last thing I tried was to improve the priority of the dcs.exe to high in the tastk manager - that helps sometimes, somtimes not.

Overall I am very unhappy with the situation, especially because the program ran as hell 6 month ago.

It runs in 2D with no major Problems, but that is not the affair it turns arround.

 

Anybody having the same issues or having usefull suggestion?

 

thanks in advance..!

System specs?

 

Don't forget you are having to produce an image for each eye in 3d, doubling the load! 30fps in 3d is pretty impressive, at least to me as i'm an ATI user and can see fps in the high teens with the mi8 and no 3d!

 

Also avoid using fraps, right ctrl pause will bring up the framerate in DCS without relying on external software that eats performance

[Latorimo]

hm, to cut down fraps could be a reason - but isn`t it a real small programm? I mean, it is a small bug (or ant) compared to DCS.

 

..I only get this "high" amount of Frames by lowering the effects (shadow, AA eg)

System is

 

gtx 570@850/2100

Intel 950 @4.2ghz

12 GB ram (standard)

win 7

In general, I've noticed a lot of microstutters with 1.2.8. Could it be related to this version?

In my case 1.2.8 has been very smooth... And your specs is very similar to mine.

 

In contrast to the previous versions, for 1.2.8 I enabled vsync and disabled force-feedback and head-movement under g-force (or something like that). Did you try these settings?

That may be a reason.

But why? DCS seems to be a really old engine with grandfather textures that are around 10 years from making..I mean it`s ok and probably necessary for a flight Simulation to work performant - but infact it doesn`t do proper - actually.

I just tried and tested it - and it really makes a difference..!! Thank you very much!

The stutters are just there but significantly reduced and thankfully not that overwelming as before - this programm more and more turns out to be a myth with some or more different and difficult personalities in it..

 

Thank you again and I wish you a gently and nice weekend(maybe with flying:thumbup:)

You are welcome. Glad to be of help. :)

I used to have microstutters because of music playing in the background (pandora, wmp, etc). I was able to overcome this by making a RAMDISK for my temp folder in windows. No clue if any of this helps, but there it is!

I previously messed with a lot of settings and found the best FPS for me was also with Vsync enabled, but importantly don't tick the 'disable aero interface' box (not sure why, but makes a measurable difference).

 

However, I haven't tried disabling force-feedback - will give it a go!! :thumbup: Do you know why that makes a difference?

I don't know. My guess is that forcefeedback is calculated on the already-overloaded CPU. Disabling that will of course free up some CPU muscle for more relevant things...

With the beta 1.2.8.27915 it now runs like a charm. As I realized that version has a framelimiter included which makes it much smoother. It also turned out that an older driver gives me 5-6 more frames:

(I had it on the hdd and just tried it for testing purposes)

 

Outlined it all (with the friendly help of Blackbelter):

 

-tick vertical sync

-detick force Feedback

-set priority of dcs.exe to "high" in Task Manager every time you see the loading Screen

-may try the recommended driver Overhead

-..hold the 1.2.8.27915 beta ;.)
