I've got a real-time graphics program (~65k lines of source code) that I've compiled and executed with the following results: DJGPP 1.12m4 with GRX 1.03 : 18 iterations/sec. DJGPP 2.0beta4 with GRX 2.0: 8 iterations/sec. All on a 486/66. I've tried the V2.0 with both the MS DPMI and CWSDPMI with the same performance results. The newer versions are giving 1/2 the performance of the V1 programs. Any ideas? Terry Abbott t DOT s DOT abbott AT larc DOT nasa DOT gov
