How much L2 cache does DOSBox use?

Hi. I'm thinking about changing CPU from Athlon XP 2400+ (TB, 266, 256 KB L2) to XP 2500+ (Barton, 333, 512 KB L2) and I'm wondering if it would speedup DOSBox at all? (CPU clock would be around 100 MHz lower) Anyone have any experience with that? t.

Re: hello AND performance

Hi. I've played a bit more with this patch and I noticed, that my problems with sound and gfx are caused by the following fragment: Copy code to clipboard 1 if((CPU_TimeSynched) && (current_tick != LastTicks)) 2 CPU_Cycles = 0; Setting CPU_Cycles >0 seem to help (in my case even 1 is enough for sfx …

Re: hello AND performance

Thanks. This patch generally works really, really well. I have some problems with dynamic core though :/. Sometimes the sound is garbled, and sometimes gfx looks like this: http://bartek.tu.kielce.pl/~tomba/dosbox/caero_001.png http://bartek.tu.kielce.pl/~tomba/dosbox/caero_004.png http://bartek.tu. …

Re: DOSBox and QEMU

Hm, it's been almost 9 month since Qbix wrote about considering it. I know it probalby wouldn't be easy, but... Right now DOSBox is perfect for VGA stuff, and it would be just great if it worked with SVGA too. One complete, powerfull DOS emulator... 😀 t.

Re: CVS 06.21 much slower than 0.61

Try experimenting with frameskip as well as the rendering functions changed a lot. I use output=openglnb, as it's much faster for me than surface or overlay (I have NV GF3). Normally I set frameskip to 1, 2 doesn't make a big difference, and higher values make it loose smoothness. Your compiler …

Re: CVS 06.21 much slower than 0.61

Hi. Ok, I've done some more testing. Original v0.61: 17000 cycles Snapshot from cvscompile (21th June): 11300 cycles Next I got sources from 3rd July, compiled with MinGW on WinXP. ./configure --disable-debug --enable-dynamic-x86 --enable-fpu --enable-opengl gave me more or less the same result as …

CVS 06.21 much slower than 0.61

Hi. Today I decided to give a try a CVS binary. I got a snapshot from 21th June, and one of the first things I noticed was a big GUS quality improvement (well, in some cases 0.61 was behaving very bad). Unfortunatelly I had to lower CPU cycles from 15000 to 11000 to get rid of the choppy sound :/. …
