Hello! So I've been running into issues when playing games that use the cave.cpp driver i.e. Donpachi, Dangun Feveron, Air Gallet, etc. Every once in awhile, not really in timed intervals, I will have the screen get dim and also shrink then fix itself back again. It only does it on the games that run at 57hz, Games like Raiden and such run fine but for some reason these games in particular are having issues.
My setup is
New Net City using a Toshiba PF Monitor with a d29c051 chassis
Groovymame 0.182
CrtEmu 2.0 with 12.6 drivers
Windows 7 x64
Pentium G4560 @ 3.5Ghz
AMD HD4350
Super Resolutions
I've added a link to a video of what it does with that particular driver, it happens pretty much when the video starts. Hopefully I have given enough info to maybe help me with this situation. Thanks for any help!
