Re: A couple of questions about the emulated 3dfx performance

So, the first question is, is the interpreter actually trying to emulate the real hardware speed, or is it just a coincidence on my machine (at least the control thread is often, but not always maxed out, but the render threads almost never are)? Total coincidence I'm afraid. There's no attempt at ...

Re: Dynarec issues

Did you ever get a backtrace for that crash? Disabling optimisation for exec_recompiler() will absolutely kill performance, it's the dispatcher for the recompiler and definitely needs to be optimised!

Re: Dev version (vNext) performance difference with v17?

Release builds are/have been built with profile optimisations. Dev builds are not. That would account for much if not all of the difference.

Re: FPU emulation

I'd be amazed if anyone saw spreadsheets with noticeable errors, but that's the general sentiment, yes. PCem's FPU emulation is for entertainment purposes only, it won't pass those kinds of diagnostics and don't try to do anything mission critical on it.

Re: Running PCem emulation in GPU

On a more constructive note, the only other thing I can think of that would actually fit a vaguely GPU-like workload is audio filter emulation. But that's probably still better off done on the CPU, kicked off to another thread.

Re: Running PCem emulation in GPU

CPU emulation on the GPU is impractical on so many levels, similar to the "make the CPU emulation multithreaded" idea that refuses to die.

Re: Running PCem emulation in GPU

I had been vaguely pondering the idea of running the Voodoo emulation as a compute shader. Might be unworkable, but possibly worth considering for some point in the distant future.

I'm pleased to announce that MichealJManley is taking over as the maintainer of PCem. While I'll still be around to a degree, Michael will taking over day to day development, and will decide the future direction of the project.

Having never actually seen a Tandy 1000 in the flesh, I'd always assumed the keyboard was like the XT keyboard in that it didn't go above F10. You learn something new every day!

Re: Building on PowerPC

Won't work - PCem would need quite a lot of changes to work on a big endian CPU, and given that PowerPC is effectively dead it doesn't seem worth the effort.
