After installing M&M7, sadly I found out there's no way to play it in D3D mode -- I'm experiencing constant and extremely frequent (>10 a second) white flashes everywhere in the game except movies. I'm running GTX780 on a Win7 x64 OS.

I searched around, but there doesn't seem to be any tangible solution, apart from "twiddle your thumbs and perhaps it'll help". So, I started trying things:
1) Turning off all other applications. Zero effect.
2) Changing video card 3D setting around. All I can do is change full-screen flashes into a "tearing" type flashes (white stripe flickering across the screen) by turning VSync off. It's a little less headache-y, but still hugely unplayable. Other settings don't effect anything.
3) Changing compatibility settings around. Zero effect.
4) Applying GrayFace's patch. Doesn't change a thing with this issue.

Is there any solution for this problem?

PS: Oh, and of course it works fine if I turn off D3D mode, but it looks so ugly without it :-\

The game runs great in 3d mode in Win8.1x64--looks spectacular in D3d mode, especially after using MMResTool to change the res to 1600x1200 and convert all of the 2d textures to 3d--100% compatible with Greyface's latest patch for the game, btw. I'm playing through right now--it's beautiful.

I use an AMD Radeon at the moment so I'm afraid I can't be of much help to you, but I highly suggest you take an hour or so and look through the topics written up in this forum--even do a search of the forum for what you need. I'll lay odds you'll find what you need...

Have you downloaded the latest version of the game from Gog?--it's actually just a later installer version, but it has a file or two the original download didn't have that make it easier to run in Win8...but here's the only direct suggestion I have for you as this worked for me (and so might work for you!)...

In playing around with the game prior to using MMrestool, I did find that 3d mode could only be turned on by running the MM7setup.exe file in admin mode with the colors limited to 16-bit support as per the compatibility menu in Win8--and once MM7setup.exe loads you should then be able to select the 3d (D3d) mode as your 3d card should show up in the menu--(and of course, for sound you want to set Miles.) This was the only time I had to run MM7setup.exe, so once the game has been setup to run in D3d mode you then link your startup shortcut to the game executable MM7.exe. You do not need to set any compatibility mode for MM7.exe...for Win8x64...! Don't set any compat mode, not even admin mode, as you don't need it. The 16-bit compat mode for your initial MM7setup.exe run is needed only so that the game will allow you to set it up to run in D3d mode. When running MM7.exe after that the game runs splendidly well in D3d mode @ a 32-bit screen depth (and you do not get the 16-bit text warning at all!)

Hope this helps!

Yes, I have the latest version, and no, I don't have any problems enabling D3D.

As for forum searches -- every kind of "solution" I could find via search is actually listed in the 1st post. As I said before, it's not like someone had a tangible solution, it's all about "try X and perhaps it'll help".

PS: Oh, and I did try MMResTool for an off chance that it'll actually help anything. No, it doesn't. I can merely experience flashes in 1600x1200, that's all.

Have you tried reverting to older nvidia drivers? Helped some people with other games.

Sorry, it's another "try X and perhaps it'll help" advice, but perhaps it'll help.

Sorry, I thought your problem was that you could not enable D3d in the game. Best of luck! D3d runs great here without any white flashes--but all this info does is let you know that there's nothing in the game software that specifically causes what you're seeing (or pretty much everyone accelerating the game in hardware would see the same thing.) Sounds most like a gpu driver issue of some kind--possibly even something as simple as a settings issue. You might try rolling back a driver version or two to see if that makes any difference.

Yea, MMRestool isn't a solution--I only mentioned it as when and if you get the problem solved MMVII is mighty impressive with it (looks great at 1600x1200.) The other thing MMRestool does for the game that I like is it converts all of the 2d textures to a 3d format useable by D3d--which just makes the game look that much better, imo. I think that with Gray Face's excellent patch, that MM7 @1600x1200 courtesy of MMrestool makes it hands down the best looking M&M game of the series ("Heroes" has never been M&M to me.) I just wish the MMResTool author had not grown tired of the games and had followed through on his promise to give M&M6&8 the MMRestool treatment, too! Ah, well. If wishes were pennies...
Hi,

Maybe that will help you: if you have Intel core PC, update Intel graphics drivers.

I had a similar problem in Baldur's Gate: EE when I was getting similar flashes, although much rarely (about 1 per minute or two). Updating Intel driver fixed it.
Okay, I had the same problem and for me it was SpeedFan running in the background BUT before I figured that out I found another way to play this with hardware acceleration activated and without screenflashes. Just to make things complete so that you don't run into other issues later, make sure you have the latest version of the unofficial patch installed from here:
https://sites.google.com/site/sergroj/mm#TOC-GrayFace-MM7-Patch-v1.6.2
Open the mm7.ini and change PlayMP3=0 to PlayMP3=1 to get music ingame

Now for the actual workaround:
1) Download the "Borderless window tool" from here: http://www.unkn0wn3d.tk/borderless-window-tool/
2) Unpack it somewhere and start the tool (it opens in the background with a small autostart icon)
3) Change your windows color depth to 16 Bit (very important - the workaround won't work when Windows is set to 32Bit color depth).
4) Go into the MM VII installation folder, right click the mm7.exe, go to the compatability tab and activate "run in 640x480" and "run as administrator" while your at it.
5) Start MM7Setup.Exe and and choose the "windowed" option and activate "hardware accelerated 3D".
6) Launch the game via the button on the lower right
7) Once the game is running, press the "ctrl + f10" keys to activate borderless window mode.
8) Enjoy!

Hope, this works out for ya!

Came here via a google search results. Found another solution. Just use dgVoodoo2.

http://dege.freeweb.hu/dgVoodoo2/dgVoodoo2.html

At the time I'm posting this, you download the latest zip file, copy the contents of the MS directory, and the root directory into the MM7 directory, run dgVoodleCpl.exe to configure the D3D wrapper, and you are good to go.

Defaults were OK. I lost the proper aspect ratio I had using the native GOG version though. But you can just set that in the dgVoodoo control panel by setting the scaling mode. I found 4:3 stretched with a CRT effect particularly nostalgic.

IMHO dgVoodoo should be included in the installation of games of this age just the same way dosbox gets bundled with games from the era just before it.

2.1 M&M7 greyface patch fixes the flashing. I used to have this problem too, and it's now fixed.

Mephalla: No it doesn't
If you still have the flashes after the patch, your issue is something else entirely.
