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.

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.

Given that you decided to make your first and at that point only post a request for stuff, I felt a little snark was in order.

3. On adding to PCem the emulation of MT-32 (and siblings, with the presumed requirement of Bring Your Own ROMs), would such an effort be tantamount to a duplication of effort relative to MUNT? Yes. Either you'd be bringing basically the entirety of MUNT into the PCem source tree, or you'd be re-im...

Re: Why is accessing a physical CDrom so slow ?

CD access just isn't efficient on PCem at the moment. All CD I/O (with the exception of audio playback) is handled on the main CPU thread, meaning that if it's slow for any reason (eg it's spinning up a real CD) then emulation will stall and performance will tank. It's something that's been on my li...
