Mac Pro 2013 (trash can) Editor performance

Development Programming & Scripting
1

Hi,

Firstly a huge thank you for making this available on the Mac, and I will caveat this with the fact that I fully appreciate that this is a first release etc, etc.

I’m running on a late 2013 mac pro with dual d300 gpus and have to admit I’m a little disappointed in editor performance. In the mobile temple map for example I am seeing editor FPS of less than 30, sometimes below 20.

Do you have a roadmap for Mac performance optimisations?

Note: I am running in full screen mode on an ACD 27 inch monitor, in windowed mode I see an even lower FPS.

Thanks!

Yes, we will keep working on optimizations and I’m sure it’ll improve in coming weeks and months. In some cases we are limited by issues in OpenGL drivers, but that should also improve with future OS X updates.

Sorry it’s not as good as you’d like yet, but I hope you won’t have to wait too long for it to get better. Thanks for being an early adopter!

Thanks for your reply, I look forward to future updates, and don’t get be wrong, UE4 is simply incredible!

Do you have plans to support the dual gpus in the Mac Pro?

Absolutely, making UE4 Editor perform great on the new Mac Pros is definitely very high on our todo list. We just received the first batch of them :).

Fantastic! Thank you!

I’m on the 8-core MP 2013 with D700 GPUs and I find that the material editor feels a little sluggish. The GUI feels heavy.

Nevertheless, I’m super impressed by the fact that this all works so well. It’s a huge step above UDK3

MichaelT took a look our workaround for an OpenGL driver bug and made some changes that should really help perf on AMD GPUs. A patch is currently being tested by our QA to verify there isn’t any fallout. But we’ll send it your way as soon as we get the green light from our test team.

Stay tuned, we’ll post a download link for the patch tomorrow AM.

wow, that’s what I call incredible support!

Thanks guys, can’t wait to try the new patch.

awesome. thanks

Try the following patch. We’re aiming to bundle this into a public fix early next week, but want to make sure it fixes your problem first.

Also, try hiding the Unreal Engine Launcher. We’ve had reports that on some Macs it helps with the performance. I’ve been able to reproduce this, actually, so we will be working on a fix soon.

12

Thank you Michael.

I’ve installed the patch and it does improve things.

I’m up approx. 10fps on the empty project template to ~45fps.

Running the sample content “effects” map is still pretty bad though drops to low teens when moving around the editor or running in the viewport.

I’ve tried hiding the launcher, that didn’t seem to make any noticeable difference.

Thank you for all of the help on this!

ya, it’s really quiet. I love this thing. I test my Mari scripts on my Windows Corsair 550D with Noctua DH14 and realized how spoiled I am by how ridiculously quiet the tube Mac Pro is when pushing GPUs and CPUs to the max.

14

I wrote teh review for Ars Technica and the thermals are really good too so there’s no concern there. I’m going to be using it inside a ventilated kiosk for Oculus Rift soon.

15

Out of interest, can I ask is the Mac Pro still quiet when UE4 is running? My MacBook Pro 2010 will run UE4 - barely - but spins the fans up to maximum and it sounds like a jet engine.

16

Hi Guys,

Is there a manual patch that I can apply - I am now building from the github source? or is there an ETA on when this change will be available in github?

Thanks!

Hello, I had a question up the same avenue:

I am getting ready to invest in a mac pro (trash can model) for running UE4. Just curious if the specs between the two base models (4-core priced at $3,000, or the 6-core priced at $4,000) would make a sizable difference; considering it being able to run UE4 well. I know it’s a loaded question… Just wondering if anyone had any input before I commit!

Below is a link to where you can configure the specs for your order… Maybe there are variables that I should consider, like memory.

Spend the extra money on the D700 GPU. The only time the CPU with more cores makes a difference is for light map baking.
