Well... I've experimented with the "sleep" timing of my AHK script but still have the same flicker issue.
I updated to the new gpuDX11.dll and everything got messed up. Reverted back to the old .dll
My OS is running Direct X 11 but my video card is Direct X 9 compliant. Should I still try and use the DX 11 driver?
Did you download the new version of Demul or just the driver?
The driver only works with v.5.7
I remember seeing some posts about the gpuDX11.dll that can be downloaded separately not working with certain cards.
You might try that one and the one that's packaged with v.5.7 to see if one works better than the other.
On the NaomiGD and Naomi2 games, it helps to disable most of what it allows you to disable under video options.
Check that the drivers for the video card is up to date.
I'm using an old Nvidia 8600GT that is a directx 9 card, but my OS (Vista) updated to Directx11 and the Demul plugin started working.
On the timing of when it goes fullscreen, I had problems when it did it during the transition (when the screen goes black after the Atomiswave logo).
Most of my scripts go fullscreen during the screen with the atomiswave logo.
Now that I think of it, there is some screen flickering in Demolish Fist during the attract mode, but the game is fine.
I've played it all the way through.
Probably just a bug in the emulator.
