Hi,
I got ue version 4.2.1 and pc:
Intel Core i5 3.33 GHz,
8Gb ram,
64 bit windows 7,
GeForce GTX 470.
My problem is that, when i change 1 little thing in simply material (for phones) then i need wait from 10 to 80 min i gues. Some times try compile 800 shaders (very slow motion, 300 is normal).
i try refresh my drivers, delete graphics drivers and install recommended and i have all time the same compile time.
That doesn’t seem normal at all, even for that CPU.
Do you have a lot of other softwares running while working? How high is the CPU usage while in editor?
I used to sit on an i7-930 and 12 gb ram a little while back and while compilation was slow the only time it took upwards of 10-15 minutes was when I compiled 30 000+ shaders.
It’s hard to say, is the editor running well other than the compilation part?
Using 20-30% with editor on and idling is pretty bad unfortunately.
Compiling shaders seems to be pretty cpu heavy, I noticed a huge difference going from i7-930 to i7-4930k, I know my old CPU ran at high percentages when compiling shaders.
Epic’s hardware recommendations say at least i7 with 4 cores 2ghz+ or AMD equivalent, so I’m guessing it might be the CPU that is causing the problem, your RAM should be enough. Your CPU will definitely make it run slow, but I’m not sure if the time you’re experiencing when compiling is reasonable or not, as I haven’t tried it on such a system and can’t find any information on compiling with something similar. Everyone on the forum just talks about fps in the editor on older systems.
Hopefully someone with more experience of compiling hlsl in UE4 on lower end systems can give a more definite answer.
Other than that I would suggest picking up a new CPU with more cores.
If this would be a possibility for you I would suggest a i7-4790k, it’s very reasonably priced a lots of bang for the buck.
But there are cheaper alternatives that would run great as well, my old i7-930 ran just fine and that one is nowhere near new.
You could always look into AMD as they’re usually a lot cheaper, I haven’t run the editor with them but my server runs an AMD FX-Series FX-8320 3,5GHz which is cheap as dirt and seems to perform great with multitasking, I use it to run 18 virtual machines with windows XP and not so lightweight softwares and my girlfriend plays games such as Rift on that system at the same time so I would guess that one would run UE4 great.
Sorry I couldn’t help much.

Hi,
I got all time google chrome 4-8 pages and unreal.
I dont have idea what i can do? Reinstall windows or unreal? Check and clean hardware?
When i dont use editor he take 20-30%, when its used (compile or something), then take more than 50%.
I got no idea, maybe pc is going to broke, thats why i create that question.
Have you any ideas?
Howdy Czester,
Thank you for your report. Would you be able to send over your DXdiag so that we may further investigate the issue that you are seeing? Also, is there any way to repro this issue? You could follow this template on how to report a bug: How do I report a bug? - Programming & Scripting - Unreal Engine Forums. Any additional information you could provide would be greatly appreciated.
Thanks and have a great day!
Hi,
all i recognise my fault. My CPU is Intel core i5 661, but i read about it more and its 2 core inside.
My boss said to me its 4 cores and i dont check this.
Thank you all for yours time, but this isue is closed now i gues.
Troubles witch dual core are on answer hub, maybe next patch change this (optymalize).
Sorry,
i read about this on answerhub. Its my first post here. Thank you for reply.
