Synthmark

Synthmark64 is a collection of synthetic tests that measure various specific operations. Shown in the table are the measured values with screen switched off and all possible optimizations that don't affect software compatibility. (That eg means all writes must go directly to C64 memory so the VIC-II can "see" the changes.) Values represent the relative speed to a PAL C64 (more is better).

(*) TODO - recheck: the test relies on the kernals pal/ntsc flag and may show 20% higher numbers on PAL because of that. As a workaround reset with disabled turbo and activate it before running the actual test

Coma Light 11 Fractal Part

(load "CV- REALT. FRAC"). Shown is time in seconds (less is better).

NOTE: This demo part uses "illegal" opcodes and does not work correctly on SCPU.
