Borderless Is not working (Help)

Hello. I have not had an issue with Halo Reach so far except border-less acting like fullscreen.
Borderless is very important for users with HDR displays, As with many games Halo MCC does not support HDR. Which means the only way to enable it is going borderless. If you try Full screen, the monitor turns OFF HDR and your left with a dull colorless display. With windowed mode, HDR does not turn off however you get the awful windows bars at the top and bottom. PLUS, with borderless you can ALT + TAB with ease. So Borderless is very important to me.

Problem is that borderless is acting like fullscreen. Theres no difference

I was invited to the final MCC PC flight and borderless worked fine as it should. However now its not.

If anyone has any suggestions to a fix, please let me know. Ive also made a bug report.

Thanks!

I am having the same issue. Worked fine in the flight several weeks back, now it just will not do hdr.

Have you tried disabling fullscreen optimizations in the compability settings?

Alright, ive made a bug report. Please do so too so this can get the devs attention.

Thanks for the reply

Right click on the file mcclauncher.exe (in \steamapps\common\Halo The Master Chief Collection) and hit properties. Compatibility tab.

I found a fix… Seems to be an nvidia driver issue, not a windows issue. Whenever I roll back to driver 450.82 the borderless works, when I update to current the borderless just acts like a non-hdr fullscreen. Had to toggle settings to fullscreen and back to borderless once after I rolled back drivers.

My GPU is Asus OC Edition 1650 Super

I can CONFIRM that this is a driver update issue. I updated with a clean install, got the same behavior. This is because NVIDIA now has 2 modes for optimization full screen that it allows. Some gamers actually use windowed modes to allow them to swap around several windows while they are recording on less laggy apps, or running taps into their game to see how the game performs in their system resources.
By using the Geforce Experience app I was able to reset this to borderless. You can also use the profile editor to create a profile for the app that forces a borderless window, without having the geforce experience installed, but you may have to wait for a version compatible with your current driver. This is a recent Change to allow users to drag a window to another monitor, etc. There’s also talk of some immersive 3d\2d games having multiple windows for multiple monitor support of an advanced HUD or control system without headset based VR.
By switching this back to Fullscreen borderless, I was able to gain some FPS and some quality too. A windowed process still uses the DMM, but it runs slower with the optimizations off in some games, faster in others–games designed with system controlled performance seem to do better, those with app controlled performance do worse. By that, I mean some games actually try to pull all the performance from the drivers directly, rather than through the system bridge that provides an interface to them. When they can access the resources, it works beautifully, when they cannot, they fall back to either a lower quality or a system bridge driver that will take a few extra cycles to send a translateable data set back to the system for sending to the resources required. Usually this drops fps and quality. I’ve been gaming on PC since the old Descent and Terminal Velocity shooters. When gfx cards were the only way, sometimes some workarounds were needed. Now that some is handled on the CPU, and all cards have some common languages like OPENGL\OPENCL, or DirectX, this is less a problem. However, some games look for specific types of threading capabilities, or similar extras, and when they don’t find it, they fall back on the system to handle it, dropping the quality a little to maintain speed and be easier on the resources of the primary system. You can still boost them with a config change in their settings, but some will not max out, or they will pop up a message warning you that it will lag.

It works to fix the alt-tab issue!!

I made an account specifically to post a fix.1.) Hit the windows button
2.) Search for “Multitasking Settings”
3.) Under “Virtual Desktops” Change both drop-down options to “All desktops”
4.) Profit.
