Descripción
Translate the description to your language and send via web-form.

This is a small GRADD filter driver that can accelerate simple 'Screen to

Screen' BitBlt operations under unaccelerated GRADD drivers. As a GRADD

filter driver, SSSBBACC.DLL is installed between GRADD video manager and

GRADD video driver, and watches over simple (but definitely important)

form of 'Screen to Screen' BitBlt GHI commands: - both source and

destination are VRAM - source-copy raster operation, with no pattern, no

transparency, no stretching and no clipping If such commands responded

software emulation, SSSBBACC intercepts and processes them by own blitters

faster than SOFTDRAW, and reports completion to VMAN. Assembler-coded, MMX

/ SSEint-ready blitters are heavy optimized for uncached memory reads and

write-combined memory writes, designed in order to eliminate unnecessary,

quite slower peripheral bus cycles as much as possible. Typically, such

slower software BitBlts may speed up to 1.5x ~ 2.5x. Highly recommended

for unaccelerated or poor-accelerated GHI (such as GENGRADD, M64GRADD in

24bpp, INTGRADD and so on) users.
