Unity Editor Really slow

Unity Engine
1

Hello,
I got a relatively new desktop pc but the unity editor is really slow. I take around half a second te respond to any clicks and de graphic stats show a frame rate of around 3-5 fps in the game view. This also occurs with a empty scene. I also tried switching from Unity 3.4.1 to the 3.5 beta but nothing changed. All other programs I run don’t have this problem.

Specs of my pc:
Intel core i7 2600k
16gb of memory (4 x Kingston 4GB, DDR3, PC10666, CL9)
Intel DH67CL B3 iH67
Asus GeForce GTX580 DCII 1.5GB
OCX Vertex 3 120 gb
Samsung HD204UI 2TB
Corsair TX850 V2 850W
Windows 7 proffesional

Anyone has an idea what may cause the performance issue?

What else is running?

3

Try disabling any forced antialiasing settings (and anything else that’s being forced) in your GTX control panel.

4

Only Chrome with a couple of sites open.

Everything was set to let the Application choose, disable everything but nothing changed.

Any luck with this issue? I recently upgraded to a new PC and Unity is running really really badly… un-usable.
spec :

asus gtx 580
core i7 3930 3.2ghz
ocz revodrive3X2
16Gb RAM
Win 7 pro x64

it’s a fresh windows install, updated to latest drivers for everything and all latest windows updates too.

starting to get frustrated :cry:

update: happens in the angry bots demo too. runs at an awesome framerate but has constant lag spikes that dont actually show up in the stats or profile view.
Also, the update of all the editor windows seems to really lag behind any input.
If I select ‘maximise’ on the game window then the problem goes away. Bringing any other windows back brings back the stuttering…

update:
seems to be linked to the heirachy window. whenever that is visible everything goes to hell…

ideas?

Only worked om my laptop lately so didn’t find a solution.

I might have to try a different video card… it’s really annoying to pull it out though. Uggh

Progress!

I killed all processes except essentials and disabled the nvidia / amd services that were running (why an amd service was running is unknown). And now unity is responsive again yay.

Now I’ll need to nail down exactly which program was causing the problem.

I have same problem. Respond after any input is too big (1-2 second).
After killing most processes is works better, but not good at all (respond ~0.5 second).
But Edtor works good on MacOSX in VMware and WindowsXP in VirtualBox on current machine, without that lags.
Tested on versions 3.4.2 and 3.5.

System:
Windows7 x64
CPU Intel i5-2500
RAM Kingston 12Gb (4*3)
Video Asus GeForce GTX 560Ti 1Gb
HDD Intel SSD 320 Series

I found reason why it happens - if whole memory consumption (for all running processes, not only Editor) is not greater approx 2GB then all works good, but if memory grows higher then Editor slow down.
Tested on two separate machines with Windows7 x64, on first 12Gb RAM, on second 4Gb.
Memory consumption get from field Commit/Physical memory in ProcessExplorer.

Workaround what worked for me - start Editor with command line option “-force-opengl”.
Btw I use latest stable NVIDIA drivers (but trying latest beta too) and latest DirectX.

I love you.

This fixed my issues…awesome that you found it. I was getting tired of killing everything bar unity!

Ok, same problem. Using “-force-opengl” fixed it. I can actually work in the editor now, was making me want to smash stuff before.

So anyone know WHY this is happening and if there’s a more permanent solution?

14

I just got started with Unity and i ran into the same problem.
Luckily “-force-opengl” fixed it for me,

thank you cvet :slight_smile:

15

well i fixed it by going in to my terrain and lowering the detail distance to 0.
I just increase it when i build/run my project :slight_smile:

FIXED IT!!!
Uninstall ASUS GamerOSD. and then restart computer. For some reason it was clogging alot of things up: Arkham Asylum, Unity, UDK…
(Thanks Chrisso in the unity forums)

Hi,

I did the same thing, and uninstalled ASUS GamerOSD, then out of no where everything is efficient now.
My PC starts up a few seconds faster now.

I dont know why that was an issue to begin with, or what it does.

18

Forcing DX11 might work as well… I had to force that on the 555m to make the editor even usable - but my problem was way worse than it just being slow.

I would really love to know what it is that causes Unity to slow down. My machine was purpose built for Unity, albeit we used consumer accessible equipment.

8 Cores, 4.2GHz, 32gb of RAM, 2x ATI 7970 3gb, 4 solid state drives (1x for OS, 1x for swap, 1x for data and 1x for unity on a dedicated controller) and a ram disk for temp files. Apparently that’s not enough for Unity?

It’s running Windows 8.1 and has no problems running the entire adobe suite simultaneously.

I’d avoid using features which make Unity slow, if I just knew what they were. How about some algorithmic efficiency? Pretty please?

20

Obviously it’s much more than enough; it’s not “features that make Unity slow”, it’s some kind of bug, likely with the OS, given the number of times I’ve seen “fine on Windows 7, not fine on Windows 8.1”. For example, the issue with slowdowns on OS X when using Mavericks, which turned out to be a bug in the graphics drivers. Just because the Adobe suite runs OK doesn’t mean there’s not some problem in the OS which is triggered by Unity.
