Ok, it's working with sample grabber setting. Thanks Tom !

No, sorry. As the last GameEx update seems to be December 17, 2025, i didn't thought it was already in there. I'll check this. Thanks Tom

Could the workaround be implemented in GameEx too, because it has the same problem with nvidia 59X.XX drivers. Is it on the roadmap ?

Yes in my PC i have both a 2070ti & a 5070ti sharing the same driver. I use a passthru to the 2070 that is connected to a 15khz monitor, so the 5070ti is set a prefered GPU. But as both are Nvidia Cards and share the same 59x.xx driver, it doesnt work. With 58x.xx, no problem with this setup, videos are working. It's really related to NVIDIA Cards and 59x.xx driver problem The option "let windows decide" use the graphic card that your monitor is attached on. That is why the Mike trick works, because when you set prefered GPU other than Nvidia, videos are rendered with this graphic card, then passthrough to the NvidiaCard for display

This works but you have to enable intel graphics on your intel processor (same for AMD processor with embedded graphics) or at least have a second GPU that is not NVIDIA If you only have a NVIDIA card and a processor without embedded graphics, use driver 58x.xx or older version for now

Nvidia has abandonned some older functions with the 59x.xx branch, i don't think they will reimplement them unfortunately........Only old software are affected As you said i think Tom has to find a workaround if it's possible Stay for 58X.00 driver or older for now and it works

The 59x.xx drivers seems to broke some NVENC functions on older software. It seems that NVIDIA has changed the API .No problem at all with 58X.xx. I have the same problem as HOL2001, no video but sound of the video is playing, so it's related to video decoding. Tested with a 2070 and a 5070ti, same problem with 59X.XX No problem with 58X.00

Do you have an NVIDIA Card and driver 59X.00 ? Do you have the sound of the video but not the image ?

BTW if i am the only one complaining about this issue and noone can replcate the problem, no need to spend too much time resolving this, i can live with 18.56 😉 But you are aware that at least 2 PCs have problems playing videos with 18.64 I could have tried to put an AMD card in one of the 2 PC or downgrade driver version to confirm but i think i'll keep the 18.56 for now, it takes me too much time to debug this, and as i'm the only one impacted, i'm going to move on to something else Thanks for help your Tom & Draco, it's really appreciated

I have tested on two PCs : My game PC has 2 graphics cards, a 4070 and a 1030 from nvidia The second PC, for tests, has a 3070 Ti card from Nvidia Drivers are up to date on the 2 PCs I can replicate the problem on the 2 PCs No event in the event viewer on the 2 PCs when black screen appears with 18.64 I don't know what could be wrong between 18.56 and 18.64

18.56 works but 18.64 doesn't work, something is broken on 18.64 i think

I downgraded to 18.50 on the second machine and video are working, and there is a trace in the log. Then i updated to 18.64 and black screen again with no trace in the log EDIT : 18.56 is working too, but not 18.64

Yes but it's the same I tried to install Gamex, fresh install on another standard machine (Win 11 pro 23H2, like other system ) and it's the same, no log of launching video with black screen. Could it be Win 11 related ?

I've updated my graphic card driver, disabled the second one, but it's the same. I don't know what is causing this issue, it's a bit strange. I'll try other tests EDIT : Added a video of the problem ( you could see that my screen is very dirty 😅) Video Problem.mp4

No videos works like avi, mpg mkv from 320x240 to 1080p When i launch a video, there is fade zoom then black screen, and if i push back button, fade zoom and return to video menu I think it was working with this setup before on Windows 11, it's been a while since i played a video, but preview was always working. I'll update my graphic drivers.

Yes , just black screen, it doesn't freeze Gameex, as i can return to the video menu with back button I don't use the video information search function Is there some files in the AppData folder to clean ? I don't see a Gameex folder there

I've installed a fresh 18.64 version in another folder with default setup, just changing the video path but it's the same. I have as specific setup with 2 Video cards, could this be a problem ?

Yes, as you can see there is no trace of launching a video Perhaps i can try a fresh install but i don't want to lose my setup

I want to use the internal player if possible, external one was just for testing purpose. With default theme it doesn't work EDIT: I use custom theme that's perhaps the problem GameEx.ini log.txt

Hi, It's been a while since i played a video on my mamecabcab but it seems to no longer work. I'm on Win11Pro, i tried to change codecs (Shark, K-Lite), change theme to default one, use an external player (VLC and MPC-HC ), but nothing is launched, i just get a black screen Video preview is working well strangely, so surely not a codec problem. I can play video outside of Gameex Without problem Is this function broken on 18.64 ? Thanks

A little update with a video if it can help to identify the problem First part, i try to switch screen at Gameex Main screen, you can see that the display is frozen on TV, but when i revert it to the CRT, Gameex main screen is working again. So no crash, but unusable on TV Second part, i launch a game, so my script to switch screen is launched before the game via advanced emulator config, and we can see that it switch to TV and then crash when launching game surely because display is frozen. Let me know if you think it can be fixed or if it is too specific to my setup to be resolved Thanks 653904266_CrashSwitchingScreen.mp4

Tom, i've tested with the new dll but it's the same, Gameex directx crash error when switching screen

Ok thanks Draco, I've tried on another PC to switch screen between two LCD monitor at 1920x1080, with one graphic card ,and the problem doesn't appear, Gameex works without problem switching from one screen to the other one. On the PC that has problem switching screen i use a GTX 1030 for the CRT and a RTX 3070ti for the TV. Both use the same Geforce driver So yes the problem seems to appear specifically with 2 gaphic cards

With scaling 100% on both screen doesn't resolve the problem, same behavior With a default theme same behavior too

Good recap Draco, that's it ! With fullscreen windowed, same crashs But when i switch screen from main menu, i have a black screen on my TV instead of a frozen main menu Surely a scaling problem between 1280x960 and 3840x2160 I use a custom theme, i'll try with a standard one
