@Seiya

on 640x480 virtualpc have problems in visualization in dos mode, i will try di do the best.

note the gl dont work i will try to find a dx version VirtualPc have an emulated S3(trio) 2d only ..

Dosbox on MacOs Sux ... i have with 7500 cycles the same speed of Pegasos 2 on AOs4

Would respond to it, but it was locked thread.


so do you suspect a purpose of locking a thread is to have another opened on the same matter? good luck with that.

old x86 hardware (athlon64 x2 5200) emulate PowerMac with MacQuake
Powermac emulator is mono thread..

audio problems only with this games..,but it's fast and very smooth

Im sure shapeshaver on the PowerBook will be more faster of this pc :)

while.. seriously. i think the speedup of an 64bit os against 32 version may not be significant if any.

It depends primarily by the microprocessor architecture.

The x64 code on average is faster than the x86 one. The same applies to the new ARM64 (ARMv8) architecture compared to the 32-bit one (ARMv7). In both cases the new ISAs benefit from the registers doubling (both general purpose and SIMD).

The same doesn't apply to other architectures, such as PowerPC, SPARC, MIPS, where only 64-bit data & pointers are added. In such cases on average there's a LOSS of performance due to the increased data size (long -> 64 bit; not for all ABIs, but usually it happens) and pointer size, which causes more data caches and TLBs pressure.
That's why jumping to the 64-bit wagon doesn't mean acquired performance; no, it's exactly the opposite: you LOOSE performance. Unless do you want to use more than 2GB of RAM (per single application, or for the whole envinroment), but it's a different question.

Just to be clear: even x64 and ARM64 loose performance due to the increased data and pointer sizes, but that's greatly balanced (in fact it even exceeded the performance) thanks to the registers doubling.

Anyway, a 64-bit architecture (data + pointer) gives other, SOME chances for optimizations, but it requires a lot of effort (and a creative mind), and in the end the results aren't comparable to a "simple" registers doubling.

i have once compared lightwave under 32 and 64bit winxp and the on 64bit it was a little slower.

It's strange, because of the above. On average 64-bit applications are faster.

@wawa

Well, I want to show there is an interest of users, even every thread possibly could be fastlocked
or deleted. Sadly today I cant even do that. Well, goes around, comes around - such treatment of users request will return in no users.
