New bug fix released.
Fixed the two A3 workbench bugs reported earlier. Fixed STEP export hanging problem. Fixed a few color override problem under VBO.
Still no clue about VBO performance problem though. My Linux machine has only 256MB graphics memory, and Windows machine mostly likely half or even less than that. There is not much acceleration on my Windows to begin with. I think OpenGL puts the VBO in system memory if there is not enough graphics memory, and automatically swap in and out when needed, which is why I didn't see that much of improvement. But at least I do see some changes on my machine. No idea why it is so much worse on easyw-fc machine. Anyone else care to report?
