Windows 10: Games slow down after 2 seconds when you alt-tab to them

My laptop was perfectly fine until windows force-updated itself this week. Now every time i alt-tab into a game, the frame rate drops DRASTICALLY after two seconds. The only clue I have is that on my desktop, that's the amount of time VRR takes to kick in in the same situation. Thing is my laptop does not have VRR.I have already done a clean reinstall of both intel and rtx graphics using DDU but the issue remains. I'm not sure how to fix this, and it's beyond annoying. can't i just roll back to the previous version? everything was working flawlessly. i hate being forced to update because somet

Slow alt-tab


Hello,

I just uprgaded to W10 recently, and discovered very annoying problem. Since I work with modding some games, I have to alt-tab a lot, from full screen to desktop. In W7 it was taking like 1 second to alt-tab to deskop, but on W10 it is like 4-5 seconds, and I hate losing this time, it feels like 5 times longer. Is this normal, is my PC spec to slow for W10 + alt-tam games? I don't mention any particular game, because I tried many of them, and it happens on them all, old games, new games, same thing...

My drivers are up to date.

Please advice something, I still have 5 days to revert to W7 then it will be too late.

 

alt + tab not working

Just found a really cool way to make alt+tab INSTANT!!!

In the launch options write the following: -windowed -noborder





This play exactly the same as fullscreen but now you dont have to wait 30 f*@!ing seconds to alt+tab back in!

Also you don't get the little purple/black checkered effect (only in Source games) from alt+tabbing in fullscreen.

 

Weird alt-tab out of fullscreen games.

Hi Simon,

The multitasking capability of a game depends on the total memory of your computer. If you have large amounts of RAM on your computer, it can multitask heavy programs easily like high-end games. To ensure that we can provide the appropriate resolution
for your concerns with the alt-tab function, we’d like to ask you a few questions:

• What were the recent changes made on your computer before you experienced this issue?
• When did the issue start?

• Have you pressed the alt-tab key during you play Rainbow Six Siege? Or it just happen without pressing it?
  
• Does the automatic ALT-TAB behavior happens on other games?
• Do you have any other programs running on your computer while playing?
• What is the anti-virus program you're using?

• What is your device or system specifications? To know, follow these steps:
  1. Press Windows + S and type
     About your PC.
  2. Send us the information listed under Device specifications.
  
  

Moving forward, if you're multitasking while playing, we recommend that you play this game only without doing other tasks. Pressing ALT-TAB or performing a multitasking interferes with the performance of your video card, especially if you're running a heavy
game like Rainbow Six Siege. It will generate screen viewing issues like intermittently switching your game screen between your desktop environment.

For now, restart your game and do not press ALT+TAB while playing. This will allow your video card to dedicate its graphics performance on the game only instead of your desktop environment.

If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.
