Low frame rate

[SuperSix2]

Just decided to boot up and play again and have on average 15FPS what gives? I have everything on LOW even now and get this compared to high and on average around 60-80 FPS before.

 

I7-3770K 3.5, GTX 670, 16GB ram

 

I see that recommended specs have changed but really that much a difference? Yes all drivers are up to date.

Guys, if you're using NVidia try reinstalling the graphics driver & purging the shader cache. Worked for me, no stutter/FPS related problems whatsoever anymore.

[OldE24]

Nvidia shader issues....NO NVIDIA HAS GOD DRIVERS ONLY AMD DRIVERS SUCK....ahahhah

 

 

 

suggest useing the GURU3d DRIVER CLEANER if you think you have a driver issue.... and nvidia had driver issues last week i know.

Hi guys,

 

This might be a workaroundmor than a solution, but I found that disabling forest tree shadows and putting tree visibility to 0 helps a good deal with keeping the fps up.

 

Disable Tree Shadows

 

To set the tree visibility to 0 in 1.5.3 go to "..\Users\..\Saved Games\DCS.openbeta\Config\options.lua" and edit the following line:

["treesVisibility"] = [b]0[/b],

 

Flying around in a Mirage 2000 at 3000+ ft I don't really care about the lack of trees and I feel more immersed by the higher FPS. There are also terrain mods that make up for it by restoring some of the forest terrain shading, see Starway Northern Europe 3.2

 

P.S: I have a late 2015 retina iMac with 24Gb Ram, 4Ghz CPU, R9 M395X 4Gb. I'm running it at 1440p and having an enjoyable experience.

Why ED does not improve the liquidity of DCS? All have the same problem why we can not normally just have fun all the time that we are stressed .Bardzo please ED teeth in the next update it took in August

I've just tried both. No perceivable difference. Also:

1. The forest trees are still there if you move the camera close enough. 10 meters or so.

2. The trees bundled with structures (in the cities) are still there all the time.

My performance has gotten poorer as well since the 1.5.3 update. 1.5.2 was smooth as butter.

 

Same here. Massive FPS drop.

[SkateZilla]

Choose LOW Preset, then Drop Everything to Low.

 

Slowly Add back detail until you lose FPS,

I reverted to 1.5.2 view distance luas and it helped some.

 

Toyed around with LOW settings also as you suggested, but the impact was minimal.

 

 

 

Since I'm far from the only one, it seems that 1.5.3 has serious optimization issues.

 

Please look into it.

It was so beautiful past performance

[Slipp]

Yes, 80+ fps all the time.

 

Now it's 25. :(

[Slipp]

Ok, I managed to find the culprit.

 

It was not the view distance, it is the shadows.

 

Shadows turned off make my FPS go up to 80's on the ground near a big city and 120+ frames in the sky.

 

Shadows on low make my FPS on the ground fall to 40ish near a city.

 

 

Shadows on medium or higher cause FPS to fall to 20 or lower.

 

All other settings are on high at 1600x900, 2x MSAA, 2x Anistropic filtering. Trees at 15k, preload radious at 100k.

 

 

Computer: Win7 64bit, I5 3550 3.30GHZ, 8GB RAM, GTX 560. Computer is 4 years old, so it's not cutting edge. Time to upgrade RAM and video card.

Gonna test that on my PC aswell now.

[SkateZilla]

1.5.2 -> 1.5.3 Had some changes to view distances, on mobile so I cant search for the LUA to download if you want 1.5.2 performance back, outside of that, only option is to decrease view distances and presets.

Thanks for the Recap, completely missed the part about trying old 1.5.2 settings.

[Windsortheater]

We know that, we acknowledged that change, and modified our settings accordingly. But as others and I already have said, it didn't solve anything

 

Just incase someone says I am generalizing it...

Now... on my testing part...

I turned shadows from LOW to FLAT and I literally gained x2 the FPS I have (can reach up to 70 FPS sometimes)... the problem is the RAM bottleneck is still there, and the game keeps freezing and stuttering constantly (game unplayable).

Just loaded up the game, joined virtual aerobatics server, hopped into an aircraft and the game already takes up 6 GB 300 MB (and keeps wandering around there since there isn't much more RAM left... so I think it begins to go crazy with my hard disk... not good.)

 

Tried the same with VISIBILITY settings to LOW (it was medium before, and before that it was high, but that didn't change anything) and the results were.. uhm not amusing....

Loaded up the game, joined server, hopped into aircraft, RAM is already 6 GB 300 MB... not a single change. In some seconds the game reaches 6 gb 500 mb and the pc is, well, totally freezing again.

 

Dear Eagle Dynamics Team,

If you could only fix the damn RAM problem... this game would run beautifully.

I can't keep telling you how it doesn't work, you won't listen...

Visibility changes did not change a single bit, so can't blame it on the 1.5.3 update. The game is unplayable since EDGE and they kept telling me it was still in beta, okay... so I kept waiting and waiting and the results are the same.

The game would run fine before EDGE. It was playable. I sincerely can't understand how you guys even remotely run it. It's probably because you've got 16 GB of RAM. Well I have 8 GB, trying to run it at the lowest settings possible, and the game is definitely NOT playable in any way.

Sorry for my constant rants but I'd like to keep using this sim. I hope you also understand that I paid for something that doesn't work anymore.

I truly tried everything I could. My apologies.

 

Sincerely,

Just another miserable user on the net.

 

P.S. as I was writing this my game tried to push it towards 7 GB of RAM occupied and locked up the entire the PC for some minutes... ED... please ?

 

I am on 8gb and have no issues even when vram is maxed on my 970gtx. I run off SSD. do you have an ssd you can try?

I was on the same situation before upgrading to 16GB of RAM.... an SDD will decrease the loading time, sure, but won't solve anythings related to the RAM usage. Simple, with 8GB of RAM on a multiplayers server, with both flat shadows enabled, no more than 15/30 MN of game before crash, not to mention the BIG freezes. 16GB solved the problem, but RAM usage is very high, often 9GB+ in multiplayers.

and 10 years ago we'd have OMG OMG this game uses 1GB of ram... time to realize, like with everything else, things change... including the amount of ram computers need.

 

ram is basically the cheapest part of a PC... and I'm glad there are games out there that actually try to make use of the full potential of PC hardware.

 

games being made for consoles limited hardware, then ported to pc, or the dude that decided his 8 year old core2 (or 2 year old AMD system) is still plenty good enough blow chunks. especially if, without those limitations, so much more could have been done.

 

please don't try and take away one of the few games out there that actually push PC hardware, there are so few of them.

 

having the bar set at the lowest common denominator for hardware limits just holds DCS back from all it could be.

I totally agree with your comment, i'm not complaining about this.... threre are very few games who use our hardware at his full potential, so if this game need 16GB of RAM, i'm ok with this, this is progress and it's still on BETA stage, wait and see how it will improve in the future.... but i really want to know why V1.5.xx use so much RAM compared to 1.2.xx with the same map.

[Hadwell]

more stuff happens online than offline at any given time I guess... more things loading into memory than in a single offline mission?

 

what was the last offline mission you played that had... su-25's, su-27s, su-33s, mig-29s, mig-21s, f-15s, m2000cs, A-10s freaking ka-50s and hueys multiples of some of them all flying simultaneously?

Also, if people could post their system specs (complete specs) it could go a way to well helping nail what's going on... because not all players are having problems, only some.

Same here, laptop i7 670M, flat shadow and low texture.

Solve performance issue moving from 8GB to 16GB.

 

Yep I'll upgrade anyway to a desktop ASAP.

16Go solve an issue caused by 1.5.3 but 8Go of ram or not, it's a fact, 1.5.3 is terrible for many of us, I stopped flying on DCS for that reason, it's just unplayable, I don't want to add 8Go of ram, they are useless for what I'm doing...

 

I REALLY hope they will come with a real fix in few weeks, at least giving us explenations.
