UAE JIT BETA 3 (Switch to Ludicrous Speed)

@tlosm

The program is "DCTBrot" on Aminet.
Thanks for reminding me to add that information to the Youtube description.

@logicalheart

What config do you have ?
On my Pegasos finish the rendering couple of seconds before your video :)

Edit an X1000 :P i see now in the description ;)

Soon i will test it on G5 ;)

@logicalheart

In that video, is that my X1000 build, or Rachy's official beta release? The X1000 specific build should be at least twice as fast as the non-X1000 build (both JIT).

I will send you a PM.

Quad G5 2.5ghz finish the rendering 15 second before the X1000 and 13 before the Pegasos2 with jit mode enabled :P

MickJT : E-UAE AmiGFX for X1000 is the fastest (SDL version eats up more CPU time).

There are still some flaws : some demos crash in the middle, others not. Slam Tilt AGA cannot run any table (the display stay white after selecting a table).

Here is what I get in the Log :

And indeed, X1000 builds are faster than those from Rachy (without X1000 optimisation I mean).

@MickJT

Awesome Mick! Thank you, it is dramatically faster.

@logicalheart

Great video. What did you use to capture the screen output?

@ddni

The hardware used for this capture is: AverMedia Game Broadcaster HD

PLEASE NOTE: I rarely answer this question because it's possible to spend time and money setting this up and finding out it doesn't work well. I've experimented with different hardware and software configurations so please understand if someone tries it and it doesn't work, I can't help you.

My current Host machine is Windows7 64-bit, AMD A8-6600K-APU 3.9 Ghz quad core with Radeon HD, 7200 rpm Western Digital drive, external video splitter and sometimes an external video transciever.

@MickJT
Can i get a PM too?

@logicalheart

Thanks. It certainly seems to be working well for you!

@K-L Quote:
For clarity, does this crash only happen with the X1000 build, or only with both MickJT's builds (or with JIT in general)?

CrisH : indeed, I should specify.

For the demos, I'm talking about X1000 specific builds.

For Slam Tilt, Beta 3 from Rachy also crashes (on X1000).

If there are any problems that happen only when JIT is on, then please specific which build it is (Rachy vs MickJT, X1000 vs Generic, AMIGFX vs SDL).

In the future, the X1000 specific build won't be needed, and the system can be detected at run time. But for now it needs to be tested and compared to see if it has any specific problems that the "standard" JIT build doesn't have. I only have a Sam440ep-Flex.

Even if there are problems with the generic build, please try with Rachy's own official beta release before reporting any problems to him.

@MickJT

Guys if you are using Whdload you have to disable in the whdload the cpu cache
Information on the game icon and in tool type list write NOCACHE
And everything run good :)

Keep in mind, if you turn the CPU cache off, then JIT is disabled. You wouldn't want to do that with every game, especially the ones that benefit from JIT. The only reason it isn't running good now, is because the JIT is in beta and has some issues.

@MickJT

On small machine is like this.
on X1000 , G5 and G4 for now is a good compromise ;)

on old euae and old eue jit too (all version) Ghost and goblins was not running right now is running great! but with cache disabled because if cache are on the game missing a part of spites

X1000 version from MickJT is a lot faster. AGA demos from 2000's plays nicely. Only emulation itself has some graphics problems sometimes.

I hope people paid attention to Almo's latest blog, and are emailing him about JIT problems (rather than expecting him to bother reading every damn forum).

Just make sure the JIT problem occurs with his official beta, rather than only one of MickJT's unofficial builds. And include as much info as possible, including exactly which game, what Amiga system, what the problem is, and anything else relevant.

@ChrisH

dont worry im stressing almos with all problem im encountering during emulation :p :p
