I use unreal 4. I don't know if this is the problem with macos version of something wrong with my specs. I use macbook pro 16, Intel i9 8core 2.3 ghz, RAM 16Gb, VGA AMD Radeon pro 5500M. It's laggy and slow. If i click a button seems that i can feel tiny bit of delay.
It took about 25sec to load empty vr project.
Everytime i start unreal, it always do 'compiling shaders..' which always make my whole system slow. is this normal? compiling will run everytime i start unreal engine and took more than 1 minutes to finish.
I only have 1 test project in unreal folder , it's just simply empty project.
Anyone mac users and have the same problem ?
Thanks

I have taken the "default game" (tables and chairs) of Unreal Engine 4.26, and packaged it for the Hololens emulator using these instructions.
I can launch the latest Hololens emulator (10.0.19041.1136) and install the Unreal application, and an icon shows up for it in the apps panel. But when I launch the app, the entire screen is black. When packaging the application for Windows (64 bit), the application works just fine.
What could be the issue? Older versions of Unreal Engine work fine, in particular I have verified that Unreal Engine version 4.25 works with the emulator.
Other perhaps relevant info: Intel Core i7-5960X, Windows 10 version 1909 build 18363.1440, NVIDIA GeForce RTX 2080 Ti, Version 456.71.
I have also used the Unreal 4.26-chaos engine, completely fresh. I choose a blank project from the Games category, C++, Scalable 2D or 3D, raytracing disabled, mobile/tablet with starter content. Then add the Microsoft Windows Mixed reality plugin and the Hololens plugin. In settings I get a signing certificate and define a project name, using Windows SDK version 10.0.18362. Again, no joy. The same thing, just as a Blueprint, not a C++ project, also does not work.
Also checked Hololens emulator version 10.0.19041.1117. No joy.
We followed all the steps exactly per docs including the “run in VR mode setting” in packaging and reproduced this issue today.
So, we are going to recommend to you to file a defect over with UE 4.26 via Unreal Engine Support | Get Help and Customer Service for UE - Unreal Engine. Besides, you can also open a support case via http://aka.ms/hololenssupport for free to discuss further too on anything we can offer for HoloLens 2 emulator/device:
The issue in the Epic's article. You should enable the "start in VR" option in Project > Description > Settings as from
https://learn.microsoft.com/en-gb/windows/mixed-reality/develop/unreal/tutorials/unreal-uxt-ch6
It was added in 4.26.
And we don't support Unreal 4.26-chaos yet. Please take simple 4.26.
I just want to ask, im running flutter with vs code and android emulator using my Acer Aspire 3 (Ryzen 5 2500u and 8gb ram 6.9gb usable).
When i run the emulator suddenly my laptop was slow and when i check task manager my ram usage is reaching 98-99% due these Open JDK, vscode, emulator, dart, etc. Is it normal? I saw the requirement on flutter website and i think my spec its not problem. Any one know how to fix this issue?
Sorry for my bad English Thanks in advance.
This is a very common issue that I faced personally. After wasting a lot of time at the slow laptop, I decided to upgrade my RAM & now it works better.
Assuming that a normal Flutter developer uses the following programs at any given time -
Chrome (~1.5 GB)
(Obviously for StackOverflow, Github, Music, Surfing etc. Minimum 5 - 8 tabs open)
VS Code (~1 - 2 GB)
For running project(s) (Sometimes I have to switch b/w multiple projects)
Emulator (~1.5 - 2 GB)
Easily consumes a lot of RAM.
Your OS (Windows/Linux/Mac (~1.5 - 2 GB)
Your OS may consume 1.5 - 2 GB RAM with no programs running. If it is consuming more, then try restarting your laptop.
I have upgraded my RAM to 16 GB now. Now, my normal usage goes to 7.6 GB (around 50% RAM usage).
If you are using Android Studio, then you will have even less RAM. It is really heavy (2.5 GB+, in some cases). I personally use VS Code as it is light-weight.
An alternative can be to use an actual mobile device, instead of an emulator.
My computer with Intel Core i7 - 4770 and 12 GB RAM is much worse.
Android Tablet Emulator used up to 3.96GB RAM. 8 Tasks of Dart.exe used up to 3.6GB of RAM. VSCode only used up 1.6GB. I only open one Flutter project, one Node.js project.
I used the recent version of Flutter 3.04. The computer is so much slow and very lag. I only opened one Edge browser too. I really hope Flutter team can fix this thing. I don't have any budget yet to buy Android tablet for this startup project. Android emulator is my only option.
I have recently ported our application from Qt5.5 to Qt5.12.1. On i5 processor Windows 10 the application runs fine. However on i3 Windows 10 Pc's we get a nothing but a black screen. The application runs fine on i3 Windows 8 though.
On further digging, we found out that the issue occurs only on devices where OpenGL version is 3.x and it works when the OpenGL version is 4.0+. That's why it worked in i3 windows8 which has 4.0 version of OpenGL.
For Qt5.5 it works, but if we port to even Qt5.6 it does not work. We cannot find anything on release notes or known bugs from Qt. We are using OpenGLfunctions and QOpenGlWindow.
Information from the logs of Qt5.5 build:
glVersion 3.1.0 - Build 9.17.10.4459
Information from the logs of Qt5.6 and 5.12.1 builds in the same machine and same environment:
glVersion - OpenGL ES 2.0 (ANGLE 2.1.0.57ea533f79a7)
I would like to know whether I am missing something that I should do while porting Qt versions? or is it a bug in Qt?
How can I force Qt to use available OpenGL version instead of using ANGLE?
I would also like to know if we can downgrade OpenGL version of the windows 10 to re-create it easily on other devices as well for testing purposes.
Thank You.
I have a problem with android emulator here My Android emulator cannot start. Error in load OpenGL lib but I have corrected it. But my Windows continuously crash BSOD critical structure corruption so I've moved to Ubuntu that I installed with alongside Windows before. But this time I met a very confusing error. Every time I use the mouse to drag and drop the item in the preview panet to layout xml then Ubuntu automatic logout immediately. And that is android > 4.0 layout. Android 2.2 layout everything work fine.
And the GNOME image viewer of Ubuntu have same crash like that if I use mouse to scroll/drag my image.
I spent almost time to find out my problem on internet but no one have that problem like me. Please help me.
My Ubuntu: 13.04 Raring 64bit
JDK: 1.7.0.25 64 bit
Android SDK: r22.01
GPU: AMD Radeon HD 7600M
I am trying to use the blackberry 10 emulator on my Core i3 laptop, but the performance is horrendous.
I am using Windows 7 and the BB10 dev alpha simulator image. I am using the safe option when booting up BB, because without it there are weird visual artefacts.
The emulator is unusably slow and I have enabled 2 cores on the VMWare emulator as detailed here:
https://developer.blackberry.com/devzone/develop/simulator/simulator_improving_performance.html
What can I do to improve the simulator performance? It takes more than half an hour to boot the simulator and it is almost completely unusable.
I found the problem. All I had to do was to reboot, enter my BIOS by pressing delete, Go to CPU settings and enable Virtualisation. This made a huge difference. Can't believe I missed that in the documentation.
The simulator is notoriously resource hungry. Your problem is probably a combination of CPU, RAM and HDD. Lack of RAM is the main culprit. I find that anything less than 8GB and it runs like a dog.
Ideal setup is:
8GB RAM
Solid State Drive (I have a Samsung 830 and it is lightning fast)
Sandy/Ivy Bridge Intel i7 CPU
