Framerate drop in Twiklesoft's Rally Raid & Barrage Tribe

[silkworm944]

I really enjoy playing Rally Raid and Barrage Tribe as they are excellent shmups but no matter which combination of graphics settings I use in the config of both games (which prob both use a similar or same game engine) I always seem to get a slow down here or there.

It seems to be going along fine at 60fps and then will drop as low as 45fps, with noticeable slow down of the bullets and my ship, at points in the game where there doesn't seem to be a whole lot more detail on the screen that would cause quite a significant drop.

The config is in Japanese but I've tried just about every combo of settings and haven't been able to fix the problem. I have a fast desktop computer with a GeForce 8600GTS running Vista and also a laptop with integrated graphics running XP and have the same problem on both systems. The games are pretty old now so my hardware should be more than adequate, particularly my desktop machine.

I was wondering if anyone else plays these games and has had any similar issues and found a soultion or possible explanation?

Much Appreciated!

has something to do with the frame option, either 60fps or vsync will work
