Graphic errors, JIT only

-=AgV=- · Post by **-=AgV=-** » Wed Oct 20, 2004 7:50 pm

When using any JIT-build of Basilisk II in Windows XP, the graphics look like this:

Non-JIT builds work, but are much slower. With the JIT-build I can actually play back 640x480 MOV-files, without JIT I get about 1fps

The funny thing is that I tried the linux version (in Suse 9.1), and JIT works, but is very slow, much slower than non JIT-versions :rolleyes:

So, Windows seems to be the best OS for Basilisk II when it comes to performance, but how do I get rid of the ugly graphics?

System specs:
Abit IS7 motherboard (i865)
Pentium 4 2.6GHz, 800MHz FSB
512MB A-data DDR450
200GB WD-SATA, 80GB Samsung IDE
Audigy 2 Platinum eX

I've tried 0.8, 0.9 and 1.0 versions of "JIT-basilisk".

What settings are in your BasiliskII setup?
You may just have to change a few things round to get it to work properly.

Can't see the picture you linked to, but i am guessing you have vertical stripes through your screen?

If so, you should use another build of basilisk II for windows and they will disappear.

Thanks, there were two 0.9 builds, one of them worked better. Now the stripes are gone, but the graphics in wolfenstein 3D are still corrupted (even worse), and when surfing in Internet Explorer 4, basilisk sometimes crash.

Well, at least it's better

Why are the Linux builds slow with JIT enabled?

I always had the same problem with JIT. Please, where do I download this alternate build that is immune to the corrupt display problem? I have tried this one http://gwenole.beauchesne.online.fr/bas ... loads.html
(latest build, april 2001) with no luck. Vertical stripes and garbage.
And another thing: to me, the JIT version has always seemed slower than the non-JIT. I am running Windows XP, PIV 2.8 GHz.

Do you have Windows XP Themes enabled? That causes graphics problems under Basilisk II.

Could you either attach or copy\paste the contents of the BasiliskIIprefs file inside your Basilisk II directory? I believe you may not be using the correct BasiliskIIGUI for JIT, plus I can see if your prefs have any known configuration setting problems.

I'm happy. Just installed Fedora native (finally not an emulated machine). It's so fast compared to what it was in VPC, And it looks great.
Now to the point: I tryied Basilisk II (on linux of course) today and got to the same conclusion: running it non-JIT works faster! how can that be?

You most likely misconfigured B2 JIT prefs on the Linux side. Since the Windows version is ancient, it used different options than current B2/JIT code on Linux.

For the graphics problem, you really ought to try recent enough code from CVS. Latest changes to the JIT dates back to Oct-2003.

Isn't there a patch I can apply to the current source to make it JIT? Or generate a patch from the JIT build?

IMO, a properly configured Basilisk II JIT may seem a little slower at first, due to the JIT process busy optimizing things. But if real world benchtests are run, Basilisk II JIT wins in every test except against Executor decompressing a BinHex file.

So, if I want the basic interface to work quickly, I would use the standard build, and if I want the CPU to work quickly, I would use the JIT build. Got it. Thanks.

I'm still waiting for someone to post a link to download a recent build of the JIT version for Windows

I don't believe one exists.

AgV is using Windows. Cat_7 said "get another build". AgV said "there were two, and the second one worked". Well, I only found ONE build and it doesn't work.

Hello,

There are the, I believe, 1.42 and 1.41 builds. The 1.41 build doesn't give graphic errors.
and maybe there are even two different 1.42 builds

look here:
http://gwenole.beauchesne.online.fr/bas ... loads.html

or here for the non-jit versions

Arggh, sorry, I have not noticed people were speaking about the Windows version. Basilisk II is Open Source, so if people are willing to port it to Windows, they are welcome.

Anyhow, there is to be a new B2/JIT snapshot for Linux since the JIT now works on x86_64 too.

What do you mean 'snapshot', isn't there a CVS server for B2/JIT? Why would people use snapshots when there is a CVS server?

Mac Emu · Post by **Mac Emu** » Sat Nov 06, 2004 7:43 am

I would think it's mainly for people who have problems compiling from CVS and just want to run Basilisk II on Linux without development packages being installed. Plus it's a build set in stone which can be widely used and serve as a comparison to later CVS builds. Probably other reasons too.

Can't you retrieve an older set of source files from a CVS server? As far as I know, it saves old versions, however I have never used this feature.

That, or could it be perhaps that you are using WindowBlinds?
It causes havoc in PearPC, so maybe also in Basalisk II?
I know WB has a per application setting, so that you can tell the GUI skinning program to just not skin Basalisk II.

I can confirm that -=AgV=- bug was fixed in Linux builds long ago. This was caused because he uses a Pentium4-based core and condition codes handling in BSF instruction processing changed.

I have just committed an improved variation, with less register wastage (i.e. faster), from Amithlon to CVS.

The 64-bit JIT is now also working slightly faster than before, provided you have POSIX shared memory support (e.g. /dev/shm is mounted).

Update:

JIT in WinXP works perfect, after replacing my FX5900 with a new 6800GT.

It's very strange, but I'm not complaining, as long as it works

The speed is quite impressive. Try playing Wolfenstein 3D without the speed limiter, it's impossible.
