7.2 FPS Pocket Quake on new Xscale

Nope still crap.... Toshiba will have support up next week to take complaints on performance hopefully then we will get somelight shed on it at this point I think we are leaning towards the OS not being optimized and this also being the reason for delays on others shipping units....in that hey are waiting for Microsot to fix it Toshiba has a workaround in place but apparently it is affecting performance.

While you're waiting, could you test PocketSNES and PocketGB? I'm curious to see how fast the GameBoy Advance module runs on PocketGB and how fast PocketSNES runs. You don't have to give benchmarks on them, just tell me if they run fast with sound.

Robotbeat, what have you done to optimize it for XScale? I'm just confused because I thought it was just an ARM instruction set, it should all be identical...

Kzinti, you are correct. However, that's only because there are only SDKs for .NET in EVC4.

Now, when I was trying out another (CE.NET) library that I thought might be optimized for XScale (it wasn't) for EVC3, I was able to have it compile and it worked fine on my iPAQ after I found the right include files from an older PPC SDK that the CE.NET SDK that I was currently trying didn't have. EVC4 has compiler optimizations for XScale. The documentation for EVC4 says that all I have to do to enable them is to add the /QRxscale flag, and the compiler will do the rest. Because of this, I have plenty reason to think that this will work.

It sure is worth a try!

Robobeat: that's really interesting. So that means the binaries compiled with EVC4.0 will run on PPC devices?

If I use EVC4.0 and target MIPS, I will be able to run the program on my Casio E-125? I simple have to work around the includes/libraries issues?

I guess I will start experimenting with this... I don't care much for the Platform SDK aside from basic Win32 stuff like file IO and GUI.

In the end, if I can get C++ exception handling working on PPC I will be one happy guy!

I'm not completely sure, but I don't know why you wouldn't be able to get EVC4 to spit out something that Pocket PCs can handle...

I am guilty of the following sin: assuming.

I was *assuming* the resulting binary format would be incompatible or would need some .NET specific libraries (DLL).

Since you got something working on your iPAQ, I was wrong in my assumptions...

Thanks a bunch!

I didn't get it working on my iPAQ, yet. I plan on doing that, though. I haven't gotten the chance to really do that, because of HD space. I had to delete some SDKs that I needed to have for it to work in order for me to install EVC4, and now I need to reinstall them. It shouldn't be too hard.

I know that you CAN use EVC4 for PPCs. It is possible and I am completely sure that Microsoft will eventually release official PPC and PPC2k2 SDKs for it when they get off their butts and do something.

OK limited programming knowledge here what leads you to believe they will make a difference in performance despite the OS not being optimized? Just an honest question....
