45 seconds to go full screen and back to windowed

[sdowney717]

On this PC FX6300 6 core CPU with GT640,

Another similar PC with phenom II x4 955 and a GT730 is instant to switch full screen and back to windowed.
Behavior was same when using an Nvidia gtx260 video card
Same memory amount. Same SSD drive.
When WMC is windowed, you can drag the size big or small with no delay
Why is it doing that?
Go full screen , you get the total black screen and wait a while.
WMC fully responsive when working full screen, just this long delay when switching to full screen and back.
I am using latest Nvidia drivers, and get sound through the HDMO cable to an HDTV

It works great on both older PC's on windows 11 23H2 version.

There are a number of threads that talk about full screen mode and/or "optimizations". A recent one mentioned disabling animations. The thread(s) about issues with specific recent Intel graphics issues may also have things to try. Realize you don't have these processors but similar issues possibly similar solutions.

This PC wih FX6300 cpu has 4 hard drives in it. One is an SSD and is where it runs win11 23H2 as the boot drive. The other 3 drives are a mix of linux system drives and a win7 drive.
I put an Nvidia GT640 video card in it. It uses DDR3 memory 8gb

I noticed when WMC starts, those drives begin to spin up, I can hear that and after some seconds go by, WMC starts playing live TV.

I also found out one of those drive file systems was damaged, could not be read. I wiped the drive and reformatted NTFS

Now WMC begins to play live TV within 4 seconds of starting, sometimes!
And full screen is 7 seconds sometimes! So it works faster now.
I think WMC is probing hard drives, looking for shared folders or something!

Now going from full screen to windowed or back again is about 8 to 12 seconds, it is very inconsistent on how long it takes, but is a lot faster than what it was in my first post.
Maybe if I unplugged those 3 other drives it would be almost instant?

Strange but my other WMC PC win11 23H2 we use all the time of a similar AMD AM3 Phenom ii x4 955 CPU and slightly less cores and uses only DDR2 memory of 8gb, has 4 Mult terabyte drives inside and has no delay switching windowed to Fullscreen and back again.

Got some more info.
I setup WMC to watch shared movies and recording from another PC that also runs WMC
WMC when opening a shared movie file with mkv extension is instant playback

WMC when opening a shared tv recording wtv file is a long delay, then it plays back fine!
What is going on as WTV files are native to WMC, yet it is having some issue with them?
CODECS??

I found out something odd.
I have a cloned copy of win 11 from this drive. IT is a spinning hard drive WDC
WMC on the clone Works perfect, full screen and windowed, instant switching

WMC on the Samsung EVO 860 SSD though does this long delay switching between full and windowed.
The only difference is the drive itself. See both drives are in the same PC and I can pick which one to boot from using the bios key F11.

Could this Samsung EVO 860 SSD be a dud??

I wonder what could be defective about it.
I use a WDC SSD on my other downstairs WMC PC and it has been perfect

IT is totally resolved. Unfortunately, that older PC just went poof. Something happened to the bios and it wont boot, got stuck in a weird bios boot loop and when I powered it off, it was dead. I still think the issue could have been a failing Samsung EVO 860 SSD, which kept failing smart tests with cant read LBA, etc... just as well really as that old board is not as good as what I replaced it with.
The dead board is an old MSI 7596. I had a better board ready to go, Asus M488TD-M wgich is also a 6gb/s SATA AMD chipset. It is working perfectly, WMC is super responsive full screen to windowed. Still using Win 11 ver 23H2. The newly built ASUS PC has a WDC Blue SSD of 500 gb and I use a 1 TB Hitachi drive for recordings.

My full time WMC has 5 tuners and over 14 TB recorder storage. I shared all the recorded TV with this other ASUS so can watch them also on this ASUS.

More info...
The Samsung EVO 860 drive must be somewhat faulty...
I installed 11 on that drive in an old DELL D630 laptop
Then installed WMC and setup media libraries for recorded TV
Running WMC, it indexed al the videos.
BUT, when starting to watch recorded TV, it takes almost a minute to get the video playing, going full screen and back again same long time waiting.

So I then installed win11 on an old SATA drive that came with the laptop 80gb fujitsu on the Dell D630.
WMC works perfect, no delay playing recorded TV or going full screen and back.

So the long delay is following this Samsung evo SSD.
A WDC SSD i have in two PC running WMC, and it is perfect and quick to play and go fullscreen
I dont think I will ever buy another Samsung EVO.
I own Samsung EVO, have two, and have 3 WDC SSD Blue.

ALso turned out the MSI board that poofed out on me, simply clearing CMOS settings by moving a jumper fixed the board
