Flying near trees causes great fps loss.

Check Mustang mod. No FPS impact after this:http://forums.eagle.ru/showpost.php?p=2495081&postcount=7

btw. after the 1.5.3 install it here S:\DCS World\Mods\terrains\CaucasusBase\Structures\High\E DM .

 

Its a problem of shadows on trees. It will be nice if ED will add option on/off for shadows on the tree. Its a problem in 1.5.3 and 2.0.1.

I hope Mustang will do the same mod for DCS 2.

 

Thanks for the tip I didn't know it worked..looks ok too. I'll try it and return with a feed-back.

extract and paste in "...\Config\Effects"

 

You know if you want to change some values, you should do so for all the settings, not just one. You never know what setting others use :)

Mustang's no tree-shadows mod enables my low end PC to run high visibility settings just fine on 1.5.2. Since 1.5.3 performance is terrible even with the mod enabled. Why are we going from good framerates for lower-end PC back to the 1.2 status quo of crappy performance for anything not top of the line?

Once again, because the "high" setting in 1.5.2 wasn't really high :music_whistling:

 

If you have low end PC you should be using low setting. Just because the setting name was called high, doesn't mean its actually representing high settings, which is why it was tweaked. The setting naming is supposed to be self-intuitive. The Ultra and Extreme are for future proofing, or for someone that doesn't need very high FPS and prefers even higher visuals.

 

Now, I will also add that this can likely be tweaked again as Caucasus is merged into 2.0.0 / EDGE, and also there are some issues with current game engine that doesn't allow better tweaking (or reducing) some of the settings.

 

Lastly, please use low visibility setting, you won't be disappointed (it is not as "low" as you might expect) and you will get better FPS.

If the setting naming is supposed to be intuitive that makes me wonder why it was changed in the first place...

[Kuky]

Read again what I wrote already. Settings were tweaked because they weren't good. Once more... if you have bad fps lower your visibility setting. I use 4K resolution and high setting is still very playable. If for you it is not, use medium or even low setting. Thats all there is to it.

Your wording lead me to understand something slightly different.

Kuky, thank you for information.

tested with medium visibility(before ultra) and i noticed that the 1.5.3 visibility medium setting is equal to 1.5.2's ultra.

for me, medium setting is enough to play and joy now.

high,ultra and extreme are unnecessary.(i guess high settings have too much widen visbility now)

 

 

with in game vsync and medium visibility setting, dcs running much fluent now, no stutters .:)

But to be fair, ED *had* to see this coming. Hell I would have left the current naming alone and added "ludicrous mode" option! :D

And what should I, as an owner of a fast PC, do? FPS is not a problem persay, but the stutterfest that is v1.5.3 is driving me up the wall. And the stutters are there regardless of what visibility settings I use. Ideas? Thoughts? Suggestions?

[Enduro14]

Yes shadows check couple pages back and use mustangs mod that gets rid of tree shadows and also make sure flat terrain shadows are enabled. 1.53 runs the best for me once I did the tree shadow mod and also change from ultra visibility to high

[msalama]

and use mustangs mod that gets rid of tree shadows

I'm already using it, doesn't help. Worked fine in v1.5.2 though. And the flat shadows setting makes no difference whatsoever.

 

The thing is, the sim ran 100% smoothly in v.1.5.2. Now it runs like garbage, regardless what settings I use. And needless to say I've changed nothing in the computer either, apart from updating DCS to v1.5.3. Not good...

[Enduro14]

Well only thing I can suggest is try a repair of Dcs world. Everybody I fly with has no problems including myself. I get the problems when I do set visibility to a distance my computer can't handle

Have done a repair. May have helped a little, may have not. All the settings are as they've been for a long time, BUT changing them to lower values does not help either. The stutters are irregular spikes, just as if the sim stopped rendering for a couple of milliseconds, or something in the graphics chain dropped a huge number of frames.

 

The last change this computer has seen was swapping an old GTX580 for a brand-new GTX980 in December, but other than that there's been no changes in ages. And as I've said before, v.1.5.2 ran flawlessly.

 

Everybody I fly with has no problems including myself.

 

I'm seeing many folks on this board who are less than happy about how v.1.5.3 runs.

You could try deleting your saved games folder, or at least a partial delete, maybe save your config folder so you dont have to redo your key assignments. If you have open beta, you could experiment there and see if it helps any.

[msalama]

or at least a partial delete

 

Will try that tomorrow & let you guys know how it goes. S!

[codenamepanzer]

Try to use high.lua, medium.lua and other visibility configuration used in 1.5.2.

 

ED has changed these files in 1.5.3.

[Nedum]

But this doesn't change or will help to locate the problem.

If I am at home I will upload a screen shot of my Afterburner log file.

You can clearly see that if I get high frame rates The GPU load is very high too and if I get low FPS the GPU load is low too.

This behavior is 100% coupled.

The average GPU load is 50% most of the time. 50% GPU load is nearly nothing for a DX11 game.

Yes ED has changed something but all I can see is that the overall visual effect is bad and I do not mean the low FPS. I mean the blur all over the picture.

Before patch 1.5.3 I have had razor sharp textures near my plane but now it's all completely blurry.

Bright colors get lost in the distance very fast (fog colors) but at the same time dark colors become more dark. You can see this at the moving train in the D9 free flight quick mission. Some bright colored train wagons become invisible and the dark ones get a black stripe as roof.

The overall visibility is foggier as before and at the same time the GPU is doing some rest, especially if you are not looking to the sea.

Perhaps a shader problem?

I do not know what the reason for this behavior is but I can see that this has something to do with lights and shadows.

1.5.3 D9 free flight quick mission @6000 feet, medium view distance and medium shadows I’ve got less FPS as with 1.5.2 (view distance and shadows @Ultra) and an extreme blurry picture. It’s like I would wear the glasses from my girlfriend. All is lightly blurry. The ground textures are extreme blurry.

 

The question is; is that a known bug or is it “art” design and we have to live with that?

If so, do we get an option to change/take away this haze?

This is so extreme that I can't play this game longer as 20 minutes anymore. After a short while I've got headaches.

1.5.3 is a game breaker for me. :thumbdown:

Weird i dont see any of that, although i have noticed a much improved global lighting in the pit atleast in the Mirage anyway. The ground textures yes the noise level was adjusted and also the grid i believe so its not as fine, correct me if im wrong. Its the best version yet for my machine and visual fidelity. Like guys in my flight group say file a support ticket.

[msalama]

I did. No observable change. Also tried deleting the old confing folder and letting DCS make a new one as per Sith's instructions; again, no observable change.

 

The only way I can alleviate said spiky stuttering somewhat is if I lower the configuration LUA values _very_ drastically, but even that doesn't fix it completely. So maybe this isn't actually caused by visibility settings per se, but something else altogether? Hmmm...

I think you have some loading issue, as in, RAM or maybe vRAM runs out and it has to use HDD or load new textures, something of that sort. I think the sudden and drastic drops in FPS are caused by that. You could use GPU-Z to monitor what your video card is doing, how much vRAM is used... change a few settings in game (always do one at the time and see how it affects performance).

 

On my GTX980 I saw all of vRAM utilised fully in DCS with only few MB left.

[Enduro14]

My Vram on 980 also is fully utilized in 2.0. In 1.5.3 ive seen the highest go to 3.8gb. One thing i noticed is atleast when i ran 3d, ground clutter would cause a major fps hit and also lots of stutter. Maybe put ground clutter at 0 also.

[msalama]

That's a possibility, I'll check. But it's v1.5.3 related still, because v1.5.2 gave me NO grief whatsover and ran like a knife through butter.

 

Maybe put ground clutter at 0 also.

 

This I haven't tried, although I've got it at 50m so there's not a lot to start with - but worth checking anyway. Thanks.

[msalama]

Nope, not running out of VRAM & disabling ground clutter doesn't help either.

[Enduro14]

so out of curiosity are you getting these "spikes" at highly populated areas aka cities or large forest areas?
