Might and Magic 9, black screen underwater & at night #88

Closed chrlpolk closed 3 years ago

chrlpolk commented 3 years ago

This old issue rears its head again! Game runs fine otherwise, but screen flickers and goes black when entering water, and goes black at 5pm (game-time, obviously!).

Using Experimental version, Windows 10, Dell Inspiron 620 Desktop, Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz, 8gig ram.

Edit: Yes, it does support 800x600 res.

An interesting thing happens. When I start the game, the cursor does "the circle thing" then an error message comes up that the program must close. After that, I cannot delete or replace the DLL because it says it is being used by Lithtech, However! Lithtech is not shown to be running in the task manager, not even in the processes! I have to restart the computer in order to "unlock" it.

Ok so on a hunch I deleted the DDrawCompat-lithtech file and restarted the program to create a new one to see if it would say the same thing. Suddenly, it's a much larger file! It's too long to copy&paste here so I'm attaching it.

Thanks! I made some progress, though I'm not sure if I completely fixed the issue. Please try this new test release: ddraw.zip (diff.txt on top of 27ae9affb8f78d56c1cd09cf888be9ac94c051e9)

Use the ReleaseWithDebugLogs build first. If it crashes again, please attach the new logs. If it doesn't, then just exit the game and switch to the Release version for further testing. (The debug logs make the game painfully slow and can produce hundreds of MBs of unnecessary logs.)

Started from clean install, just in case.

Same thing - cursor does "the circle thing" then "This program has stopped working" crash message.

Hmm. It did get further, but now it's not so obvious why it crashes. Could you try to get a crash dump by following the instructions in this comment? https://github.com/narzoul/DDrawCompat/issues/50#issuecomment-520162844

Edit: Please send the log with it too, just in case it doesn't crash the same way.

Sorry to leave you hanging, work has gotten busy and it may be a few days before I can get around to this again. (But I desperately want to solve this!) My solution may just be to buy an old Nvidia graphics card, it would save everyone involved a lot of hassle! Thank you for your quick responses on the matter.

narzoul commented 3 years ago

Don't worry about it, I may have figured it out anyway. I've updated the experimental release. When you have some time, please check if it solves the issue.

narzoul commented 3 years ago

I'm assuming this has been fixed. If it's not the case, please reopen it.
