Fred were talking about writing code within pb that is specialized for certain CPU instructions using like this
Code: Select all
compilerif #Compiler_SSE
procedure MyFunction()
;sse code
endprocedure
compilerelseif #Compiler_MMX
procedure myfunction()
;same function but using mmx
endprocedure
compilerendif
and with dynamic cpu it will include all of them and select on runtime

I mean compile several Optimized exes(bin/MyGame_sse, bin/MyGame_3dnow!, bin/MyGame_none)
then make a selector exe:
Code: Select all
compilerif #Compiler_SSE
runprogram("bin/MyGame_sse")
compilerelseif #Compiler_3DNOW!
runprogram("bin/MyGame_3dnow!")
compilerelse
runprogram("bin/MyGame_none")
compilerendif
and with dynamic cpu it will include all of them and select on runtime
That'd be what I'd do if it was possible...couse it's a little faster
