Slow performance near trees and bushes is back?

[mr.g-c 6]

Anyone else got the Problem with the latest beta patches, that performance gets really down when you look at a bunch of trees (the non-pine/conifer kind of Trees) ???

And furthermore it re-introduced some kind of mouse-lag, while looking around and some of those trees pass your view

Anyway i opened a ticket about it to see if i'm not the only one.

I noticed noticeable stutter too in benchmark.

Slow performance around those trees was never fixed.

[CarlGustaffa 4]

Well there were one or a few betas a good while back that significantly worsened the problem; nearly everyone would get severe fps drops by using scopes against the "tree pole" (?) and grass, as well as the old tree leaves problem.

But, I think something has happened to it, also quite a while back. I'm now able to run normal textures for the most of the time, but the normal textures looks a lot worse now than they used to when they were completely useless for me.

But I can't tell anything myself, I haven't really done Chernarus in a while.

I get the same issues since the last few beta's (ARMA2_Build_71749, ARMA2_Build_71726 and one or two before). More noticable mouselag especially around trees and bushes. The red trees are absolute killers again.

Win xp sp2. Q9650 @ 3 GHz. 3 gb low latency ram.

I am using some @proper mods, the one that forces ARMA2 not to use the highest LOD version of trees / bushes. Maybe the latest beta's somehow don't work with the @proper tweaks anymore?

Could you verify this with sbsmac's ArmAFPSAnalyzer?

Hmm, the 'inlandFlight' benchmark was meant to flush out issues with trees but if someone (Mr G-c?) can post to an example of a particularly problematic section of forest I'll happily add another benchmark.

Well, that is right, however for me only a few ones were killers like the famous "red trees". And furthermore there was no mouse-lag or "look-around-lag" when looking around near trees for me. And i can perfectly replicate it when i don't use beta-patches that its better then.

Well i notice it in basically every mission i play on chernarus.

But really Killer is now suddenly that small wood, when you start sceanrio-mission Nr. 2 (where you raid that chedaki town) - this mission is perfectly playable for me without beta..... :eek:

[randir14 10]

After installing the new 1.07 patch I tested the trees and my fps would drop to the 20's. Turning off anti aliasing would bring it to the high 30's.

I also noticed that looking through sniper scopes causes huge performance drops to the low 20's but I don't know if that's vegetation-related. It never happened to me with older patches though.

[LeadCommando65 10]

Someone should identify the exact model name for those trees/bushes/etc. which are causing the performance drop (would have done this already, but I don't know how). Only with this information the developers will be able to do a proper overlook on those issues. This way the chance would be much higher to see it fixed.

Same here, using night vision goggles, scope near trees and houses in freedom fighters mission introduces stutter, sometimes the game pauses for split of second then it continues.

No mods, settings on default, PP on low, AA disabled, VD 2016, exThreads=7

[maruk 80]

First step is to get to something isolated and reproducible.

Atm this issue is described only in general way, and it is not even possible to tell people saying they also see "horrible stutter caused by any non-pine tree" are really reporting the same bug.

Things that can help to track this problem down:

* exact location where it is observed

* what version was ok there (if possible, please verify it really still is ok there in that version) and what version is first to break it

Please note that despite you may feel this is an obvious problem that everyone should see instantly, it is not necessarily the case.

[Proton 11]

* what version was ok there (if possible, please verify it really still is ok there in that version) and what version is first to break it

In my case the problem was not there with the 71548 beta over 1.05, but exists in the 1.07 patch. Not tried the betas in-between and I cannot go back after installing 1.07.

Reproduction is trivial in my case, as simply loading Utes in the editor and starting to run circles anywhere causes permanent stutter after completing a few rounds. Mouse input is also lagging. I cannot confirm that it is caused by the orange trees, as the framerate drop occurs when just looking out to the sea, although heavily forested areas with those trees definitely worsen the problem.

Running xp 64-bit, 6GB ram, nvidia 295, i7 920.

I duplicated niverin's location/screenshots and found similar results. It makes sense that more trees on the screen at once would drop framerate, but almost a 10 FPS drop is pretty substantial. Settings are in my sig.

i will make a video of it once i'm done with my exams.

[Bouben 3]

I've also noticed significantly worse performance in forests.

[mr.g-c 6]

Can anyone of you try to remove "largeadressaware" flag from the exe with Editbin or similar? Suma thinks the changes in Memory Handling on 64Bit Systems might cause the performance issue.

I'm out of constantly PC-Use the next couple of days, as im rebuilding parts of my car, which has a higher priority.

But we should hurry, or we wont have those issues fixed in the unification patch for OA+Arma2.....

I tried and it does not help in my case, although what I am observing a general performance breakdown in the latest betas and the 1.07 patch, not just next to trees, rather everyhere. I reported it here:

http://dev-heaven.net/issues/11550

I cannot be sure, but I have a feeling that it is the same issue.

[niverin 10]

I haven't noticed any performance issues in the 1.07. The only problem for me is a significant FPS drop in Cipher and other "very scripted" missions (main Campaign etc) and these trees.

When explore islands via editor, everything is perfect smooth (60 FPS almost everywhere) but in Campaign or Cipher ... 15+ FPS drop :-(

Scripts (or AI) are too much resource hungry I think, but don't know if there is possible any improvement ... I am not an AI programmer :)

I´ve had slow performance around trees in all versions. In fact, i think i had the same in Armed Assault 1 aswell.

Check the epic drop;

No trees, 39 fps.

next time include complete set of your settings in moment of taking the screeshots like AA level

Ofcourse rendering such lovely tree's will bring the performance down! I had the same issue when I had a single 8800GTX, some tree's would kill the performance. As soon as I upgraded to GTX275 it was at lot less noticable.

Now with two GTX275's in SLI it's non existant, maybe less than 2 or 3 fps drop when looking at trees.

The two performance killers I see are "towns"... or buildings... that kills my perf by like 50% and also the campaign (ARMA2) which runs at 22fps... no higher, no matter where I look or go.

EDIT: forgot to say that my GPU's heat up A LOT when looking at tree leaves, they normally run at about 64deg, and if i look at a set of tree's for over 2 min the GPU's hit almost 82deg before the fan ramps up higher.

This heatup in the GPU and (very slight) drop in FPS means the tree's require A LOT of GPU power to render, but they are quite detailed and complex, add a lot to the atmosphere. I would suggest dropping the AA or even turning it off if you have issues. I run at 1680x1050 with 8x AA and only notice a slight fps hit when looking at tree's. With a higher res this would be worse, so either drop the res or AA :)
