I have an Unity application let's call it X it usually runs at about 60 FPS. But when I rename the executable to Explorer (the same as Windows Explorer) my FPS drops to 7-8.
This is a screenshot from the profiler when the app is named X when the FPS is about 60:
This is another screenshot from the profiler with the same app but named explorer.exe when the FPS is about 8:
This is a screenshot of the GPU usage when named X.exe:
The same app named explorer.exe:
I'm can and will rename the app to something else, but I'd like to know what causes this and how I can figure this out on my own.
Things I've tried:
Disabling my AV which is windows defender and restarting with no effect.
Trying to reproduce it on a colleagues PC, with no success.
This makes me things that it might be specific to my machine and that maybe some process is trying to make some API calls on the other Explorer.exe and somehow affects my app.
In case it's relevant
I'm using Unity 2019.3.5f1
It's happening in the built app both debug and release
OS Name: Microsoft Windows 10 Pro
OS Version: 10.0.18362 N/A Build 18362
System Model: Alienware 17 R4
System Type: x64-based PC
Disappointingly the issue was cause by the fact the my windows was using the CPU graphics card instead of the dedicated one when the app was named explorer.exe.
To change this, I had to:
Go to Settings > System > Display > Graphics Settings.
Browse and pick my app.
Select my app from the list.
Select Options.
Select High performance.
Select Save.

This made my app use dedicated GPU instead of the integrated one.
I've got a personal laptop (running Windows 10) which I use at work where I connect it to an external display using extended display mode. I keep all my personal icons and windows on my laptop display and store all the work-related windows on the external display. Whenever I unplug it, all the windows and icons from that display are merged into my laptop screen. I want to programmatically prevent changing anything on my primary screen when the secondary is disconnected. I'm currently writing a utility app for a variety of small productivity improving features and would like to add such feature in it. I can think of two ways to achieve this:
by tricking the system to think that the external display hasn't been
disconnected;
or take all the opened windows and icons on disconnected screen and put them on separate virtual desktop.
I was looking into Windows GDI Device Context Functions but haven't found anything about display connection/disconnection events. How can I detect display disconnection (and get that display's opened windows and icons)? Anything that can be done using C#, C++ or PowerShell scripts would be much appreciated!
I have a Windows 10 64-bit PC (fresh install, not an upgrade).
When I run the setup file (web or offline alike) in order to install Visual Studio (2013 or 2015, Community edition), all I get is a small black rectangle on the screen (which I later found out that this is actually the title of the setup popup window), without the actual window of the installation.
I have tried it also after a reboot, and with various "versions" of the installation files (web, iso, standalone), but it's always the same situation.
What can I do about it? VS is my main development tool and I really need it on this computer as soon as possible.
Similar problem here. Program install ok but display blank screen after launched.
Problem solved when I changed my Nvidia graphics's global 3D setting to integrated graphics.
Right click desktop
Select Nvidia Control Panel
Select Manage 3D Settings
Under preferred graphics processor, select integrated graphics.
Apply.
If you are using a laptop with an external monitor, try unplugging it and using your primary monitor to launch. This worked for me. Laptops often have dual graphics cards and I believe we're hitting some issue with the way the Installer for VS was written (likely WPF)
Once I launced it and started the installation, I could safely plug my monitor in and it kept working properly.
I'm using an AMD GPU, It was a blank white screen but when I hover the mouse over it, I can see the text events
By the way
I went to my AMD Radeon Settings and saw that vs_installershell.exe and vs_setup_bootstrapper.exe were added automatically to the Switchable Graphics list
they were with Not Assigned Option which usually is like High Performace Option
means It would run it with my ATI GPU.
So I clicked on them
Selected Power Saving Option (to work with my Intel GPU)
Which worked and I can see the window of visual studio installer back
after restarting visual studio installer for sure.
whether is your graphics card, just turn on power saving for it.
Had the same issue. Since this topic is not accept any answare, there is one from https://developercommunity.visualstudio.com/content/problem/150888/visual-studio-installer-shows-blank-screen.html
Try to open installer as Admin.
You will probably have blank screen. Do not close it!
Open installer once more.
Hope it help other people with same issue.
the same thing happened to me, i didn't do anything i just waited for it and it started showing it's status, i suggest you close other running programs to avoid conflicts and performance hindering, and try it again.
This seems like a very shoddy issue. I've run into this problem too, and I tested all solutions that I came across online. These all work:
Running the installer as administrator, which is a blank screen. Leave it open and run a second instance of the installer, which will not be blank (doesn't need to be run as administrator the second time.
Changing screen settings so that the laptop screen is not being used.
Downloading the AMD Settings application, and setting vs_installershell.exe to run on powersaving mode. Restart the installer after saving the settings.
Use a default graphics driver instead of the AMD one.
I had the the same problem in my laptop. The temporary solution is: start the installer only without the battery, if installer starts you can connect the cable, it works fine.
I had to run integrated graphics rather than my Nvdia. That solved it for me.
Remember to change it back when programming in OpenGL and DirectX otherwise you may get a list of messages staying that nothing works.
I had the the same problem in my laptop. The work around is, in device management, remove the amd graphics or start the installer only with battery.
After installing new Windows8 ultimate OS.
Brightness control keys are not working of my laptop.
My laptop model is TOSHIBA SATELLITE C660D
I search for drivers but not find suitable and working driver for my laptop.
I have the similar issue and have solved it like this
Just right click --> My Device/Mycomputer ---> Manage --->Device Manager
Then find Monitor open Monitor section
And then right click on Generic PnP Monitor and click enable
Then you will be able to use brightness keys in window 10 and 8
I have similar issue with Lenovo Y570. The software for managing fan speed does not wortking properly - it does not manage fan speed. Try to install soft which manages brighetness for windows 7 and compatibility mode.
P.S. Don't forget to create Restore point first.
Try to rollback driver to Windows default driver.
goto Control Panel - Device Manager - Display Devices - Right Click on Intel Graphics - Click on RollBack - Confirm - Ok.
I'm trying to use Microsoft's Remote Display Control (version 2.03, copyright 2000) to view my Windows CE device on the desktop (not only is it nice for my "regular" handheld device, because it makes the display easier to see, especially in zoom mode, but it is even more important for the other devices I have to test, whose screen is too dim for me to make out exactly what's on the screen (it's like the vision test from h311) - which is necessary for debugging, of course) but for some reason I am not able to enter key strokes on the device while it's connected to the desktop. I can enter them neither on the desktop/in RDC nor on the handheld device itself while connected via RDC.
This, of course, is untenable (no pun intended).
The .exe is created in XP Mode, copied to a "holding tank" in Windows Explorer on the Windows 7 machine, then copied from there to the handheld device.
Then I connect from the handheld device by selecting Start > Programs > cerdisp > selecting OK in the "Remote Display Control" dialog, then Connect, then OK (and I do connect), then run the app on the desktop in the "WindowsCE" window that RDC supplies. It allows me to select menu items, but the keyboard is broken/mute...???
Is this a known bug? Is there a workaround? The desktop is a Windows 7 machine.
Doing a "cold boot" of the handheld device caused it to come back to responsiveness, keyboard-wise. These devices are betimes more peckish than a put-upon puddle of Platypi.
