Switched To Dx10 And Now Random Changes From Full Screen To Window

Featured Replies

Hi all

 

I decided to try DX10 now I have a better pc and card, and have also installed the paid version of DX10 fixer.

 

Generally very happy, but I get these random moments when the sim carries on running but minimises and then returns in windowed mode.

 

Any thoughts would be greatly appreciated

Happens to me as well. Do you happen to use MCE?

I dont even know what MCE is!

When that happens, it means some other app in the background is taking focus away from FSX. So you need to check what is running. DX10 fixer does not run in the background, as it is set and forget.

System: MSFS2024, ASUS Rog Stryx Z790-A,  Intel i9-14900KF,  Asus ROG Ryujin III 360 , Asus Hyperion Case,Rog Stryx 4090 OC, Samsung 970 EVO M.2 SSD, 1Tb Samsung 860 EVO SSD,64Gb G Skill Memory, Asus Aura 1200W Gold PSU,Win 11 ,LG C4 48" 4K OLED Screen., Airbus TCA Full Kit, Stream Deck XL. WinWing FCU, EFIS, MCDU

 

MCE= Multicrew Experience.  Badfinger is right; something is taking focus.  Shut down other programs until you find the one.

Ah. I seldom run anything in the background, other than REX

Right click on fsx.exe; under compatibility choose disable themes and desktop composition.  See if that helps.

Thanks, Ill see what that does

I didnt have those options.  Must be something that has recently installed that is causing it.  Will have to go back through logs - might be a Windows update thing as Ive seen a few people reporting this suddenly

Right click and choose Properties and then Compatibility. You might be right about a Windows update. Come back and let us know if you discover a fix.

Im not 100% sure but I think that it may be something that happened when the graphics demands got too high.  I have dialed everything down a bit (including AA in the DX10 fixer), and it hasnt happened since

Interesting.  I'll consider this the next time it happens.  It's rare and random for me

Hmmmm..  Open your fsx.cfg, Matt, and check under [uSERINTERFACE] that :-

 

PAUSE_ON_LOST_FOCUS= 

 

is equal to "1".   If it's set to 1, the sim should not keep running in the background. 

 

Note: Graphics demand will not cause this: it is highly likely - 98% that this is caused - as most others have said - by another app taking the focus. 

 

All the Best,
