I recently formatted my new netbook and installed xp pro on it.
For some reason Touhou 6-9.5 has huge issues now, but MoF, SA, SWR and the UFO demo runs flawless as usual.
I get about 20-30fps on EoSD, PCB wont even start, IN starts after a LOONG time and gives about 20fps and StB glitches around and is also locked at 20fps when playing.
Before I reinstalled the OS I had no problems getting a full 60fps on all of the games, and for some reason EoSD runs at 60fps during the demo video and when playing replays.
Any idea what the cause of this is? I've installed the latest direct x and the drivers for the computer, so I have basically no idea what could be wrong here. >_>
EDIT:
The problem has been found and solved. Apparently if you have RocketDock installed, it will cause major issues with TH06-09.5. If RocketDock is closed down the games will work normally without any issues.
This may have something to do with how the programs are rendered as the rocketdock is a panel similar to the one found in Mac OS.
Long story short, as I said before. If RocketDock is closed before running the games, there were no issues. =)
(Phew! You have no idea how happy I am to find out that I don't need to reinstall my OS again. >_>)
