Degraded framerate with 1.2.1

[aaron886]

The FPS issue has yet to be fixed by an update. I think it will probably be announced.

[YeaImRota]

Ok just an idea, try the attachment below - it's the High.lua from 1.2.0, if some of you could try this out and report their findings it would be of great help

Mustang,

 

Thanks for the quick response. After the auto-update, my frame rates went back up to 50, and with the old high.lua file that you posted, I'm now back at an average of 55-57. However, the new explosion effects absolutely kill my frame rates down to around 15-20 when there are a bunch of them in a row. For example, a rocket salvo from the Su-25T. Hopefully this can be looked at.

[Azraeil]

While we are on the topic of frame rate, can someone explain why certain areas have intrinsically low frame rates ~30fps while other areas can have in excess of 60 fps regardless of what graphics config I use such as triple monitor setup, single monitor high or low settings (with key things always kept off such as HDR, tessellation-aa, etc) ??

 

tested with both specs below

 

system specs old: i7 920, gtx 460 sli (upgrade to single 670 2gb), 6gb 1600 mhz ram, (power supply went kaboom)

 

system specs new: i5 3570K, 670 2gb sli, 16gb 1600 mhz ram

 

I aware of the poor sli optimisations, but my question is to the cause of the apparent 30fps hardcap in certain areas of DCS world.

 

Still downloading 1.2.1, will check framerate when I install it and report back here.

Just to make it clear, there has been no auto-update for the FPS issues yet so the gains you're seeing are most likely from the High.lua alone.

 

Thanks for the feedback guys, keep the reports coming.

I use customized graphical settings, not one of the three presets (low, medium, high); is there any file I can save from my old World installation and copy into the new one, so that I don't suffer the frame rate decrease while playing the new version?

[Ike4fin]

New fire/smoke effects seems to cause poor fps for me during battles.

Would the explosion framerate problem described by yoyo here

be included in any patch? I mean, are they the same issue?

[MagnumHB]

I doubt it, or at least completely, because the CBU-87 was a problem in 1.2.0 as well. The new particle effects in World seem to be terribly optimized so far.

[Corrigan]

I remember reading that the CBU performance issues would be fixed. If they've now made all the other explosions similar, I will not be a happy camper.

Gotcha. Thanks for the help!

[aaron886]

I think, and I could be wrong, that ED is still using a pretty old shader model. No doubt it's contributing to that problem. The whole sim needs a new particle engine that takes advantage of modern hardware, really.

yup! Its the same effects since Lock on days. I think its high time for an upgrade. Perhaps make use of some of graphics card. I think so far most of this sim is very CPU intensive. With over 1 GB vid cards being standard, I think for sure the card can draw some very cool graphical effects.

Did you not notice that the explosion effects received a massive overhaul when World was launched? Prior to that, A-10C and BS were using LO-era effects (or something derived from them), which while not as fancy, were far superior to what we have now in terms of gameplay.

Agreed, I would rather have old and smooth effects until ED makes proper effects that doesn't kill your pc.

[Witchking]

I don't think its that bad. I don't have a great system..but I love that finally we have some nice smoke when cannon rounds impact the ground. Optimization is necessary, but its a nice step forward....the effects definitely need more tweaking and enhancements.

Nice try Mustang. Unfortunately still absolutely unplayable with previous 1.2.0 settings on 4,8Ghz i7/16GB Ram + GTX680 4GB :(.

[SkateZilla]

i got my FrameRate back to 1.2.0 standards (or closer too) by dumping EDs DEfault 3-Screen LUA and going back to my custom Eyefinity LUA.

 

Still having intermittant issues with mouse, and having to ALT TAB and go back, at the start of missions or when going from Mainscreen to MP Screen.

 

Renderer also takes a minute to come back up when alt tabbing (sit at a black screen, then it comes back w/ scambled UI then restores it self correctly).

Sad to say FPS drop with 1.2.1 . I actually had better frame rate with 1.2.0 than with 1.1.1.1 so I'm somewhat surprised.

 

 

Still some tweaks to do yet. But yes less FPS 50's to 30's

I've tested medium and high settings and there is no difference in performance (around 25 fps flying over batumi where in 1.2.0 i had around 39 fps there), but i'll give that 1.2.0 high.lua a try once i get back home.

[aaron886]

Once again (it's going to have to be said once a page because no one ever reads,) this is a KNOWN issue, it's a repeatable problem that affects multiple types of hardware. ED will be updating World with the auto-updater to fix it.

[Aries]

Same framerate drop here, even with Mustang's High.lua...

...from 50-60 to 25-30. :cry:

Can't wait for the autoupdate thingeye to crush this obstacle in our path of destruction...

...and, khm, peace... :music_whistling:

[BIGNEWY]

Still a massive drop here as well,

 

also my client did a small update this morning and it reset all of my exported mfd's and so on. Will it do that every time I use the auto updater ?

 

EDIT: update made a backup folder, nice :)

Frame rate has nearly halved for me. Up and about in the air has gone from 60 -> 35 fps.

 

EDIT: Oh and now I am crashing at the master server list. Hoorah!!!!!!!!!!!!!!!!!!!!!!!

low FPS in 1.2.1=>maybe a hint

 

Hello,

 

yesterday i installed DCS-W 1.2.1. And i see something interresting regarding the fps maybe.

My System is pretty fast:

6 core @ 3,8 GHz & nVidia GTX690

At first 1.2.1 seems to runs smoother then 1.2.0. In many situations @ 60fps (yes i have vsnyc on).

But if you activate any second "viewport" the framerate drops dramatic.

For example. I started in the Mustang (1680x1050) with activated mirror. I get 20-30 fps. If i deactivate the mirror (with mouse in cockpit). The fps rises to 50-60.

Another test. I started the Mustang with setting "MFCD" (i have 3 monitors). Even without anything rendered at the outer monitors the fps is low @ 15-20 fps.

Not sure that was that dramaticly before 1.2.1.

Btw.: The graphic card usage is under 70% during the hole testing. Max Alaising or HDR doesn't impact the fps.

 

Btw2: the mirror shows graphic glitches on the ground.

 

 

I would be great if DCS could use multithreading for different viewports.

This and a dedicated server i'am still hoping for.
