<pre> This problem is currently "solved" on the GLide64 side. But it reveals a
serious problem with GL_ARB_buffer_storage extension.
GL_UNSIGNED_BYTE with GL_ARB_buffer_storage extension it's extremely slow.
GL_UNSIGNED_SHORT with GL_ARB_buffer_storage extension is a little better but
is still slow. GL_UNSIGNED_BYTE without GL_ARB_buffer_storage is faster, but
not work at full speed. GL_UNSIGNED_SHORT without GL_ARB_buffer_storage works
perfect.
The dangerous combination is GL_UNSIGNED_SHORT with GL_ARB_buffer_storage
extension, that may end up destroying the hardware under the right conditions.
I quote myself:
Sorry for the delay, but I had a "technical mishap" ...my video card is DEAD,
stone-dead.
I am responsible for my unwise BIOS configuration (GART error reporting =
Enabled + PCIE Spread Spectrum = Auto) and "pushing stress" on GPU to render at
non-standard resolutions (monitor 1080p to 120Hz (max 144Hz), mupen64plus
windowed to 1400x1050) using a buggy extension like some kind of "steeplechase
generator" for benchmarking. Well, I reaped what I sowed.
