i would assume you would get more people downloading on weekends than during the week?

   nah, mid week is traditionally the busy time for the site..

 PlayBASIC V1.64N3 - Beta 12e

      It would seem the stack issues have been solved, or at least nobody posted anything that doesn't run because of it and nor can i find any local examples that fail because of it.   There's few legacy examples that don't work with newer versions of PB out of the box, often cause from tightening up or filling in some behavior, which may have been none existent  in legacy versions of PB.  

      Been disassembling a lot examples as I go, tedious yes, but the only real way to be sure about what the compiler is producing.   Noticed an oddity with Type Caching when using math short cut operators (+=, -=, ++ etc etc ) on typed variables/arrays.    Where the compiler wouldn't cache the accesses across multiple lines.  Meaning such code wouldn't be an efficient as it could be.   Had noticed this before in the Type Cache Bench Mark, but couldn't see an obvious cause.  Turned out the code generator for the math short cuts wasn't being told to cache them.  

      In previous revisions of 1.64N, this code

PlayBASIC Code: [Select]

       Me.X = Me.X +1
       Me.Y = Me.Y +1

     
       was actually quicker (at runtime) than

PlayBASIC Code: [Select]

       Me.X += 1
       Me.Y += 1

       
       Now it's the same..

       The optimizer is one of the most beneficial additions for the legacy VM's performance we're ever had.. The picture bellow shows the benchmark running on V1.64L (Learning Edition),  V1.64N3 (today's build) and PBFX V1.77.    Obviously V1.64N3 is much quicker than V1.64L with the optimizer enabled (remember both are running on VM1 runtime).  It's performing so well, it's almost as quick as the legacy VM2 runtime used in PBFX.     What's really interesting, is that edition of VM2, doesn't have Type caching or most of the compile time optimizer...   One can only imagine, how quick that'll be when implemented into Vm3 runtime.  

      This will be the release version, so get downloading and get testing !

Function Performance

      All the stack and instruction set changes has made some fairly significant improvements to the Function Vs Psub bench mark.    We're seeing about a 15-20% speed up in function calling (from the IDE) in V1.64N3 over 1.64N2 (more if you go older).    Which equates to about 1 millisecond gain per test.   Very happy about that.   Attached is a piccy of the bench marks results.   Older results in previous pages.

I'm going to test this beta =) These numbers are very impressive!

all work very well!

p.s. I tried make video to mick4fun arcade game, first i start my fraps demo then i start playBasic and PB don't appear Editor windows.
win7x64
Maybe this is not a bug, but editor.exe really not appear.

to atlus

i had exacly the same issue. i think it is fraps, because my art program won't launch if i have fraps running.
a while back i even e-mailed fraps and told them about this, but they said it is not fraps, even though i have two programs that won't launch while fraps is running.
i hope this works out.

Thank You Kevin!

playbasic v1.64 N3 still thinks it's a beta?

check pic.


EDIT:  i did not install this properly. i tried to install this as a standalone program, rather than intall it as a patch.

[kevin]

sigh, you'd think by now, people would have learn how to install an upgrade   

[BlinkOk]

you think by now the product would auto update like every other product

[kevin]

you think by now the product would auto update like every other product

   No trolling please..   Wish we'd thought of it..   Far from concept,  this was tried at one point.  But it doesn't solve the problem.     To be freely available, all updates must assume must they're being installed over an existing 'complete' version, if the user manually selects a new install path during installation, then it won't work..       

 
 

[stevmjon]

blimey , sorry about that.

i was too excited to install this, and completely forgot the correct method.
thanks for the update.

[BlinkOk]

not trolling at all. every other product does it and does it well. just solve the problems

[baggey]

Keep up the good work KEVIN. A little bit of performance here and there makes a big difference!  ;D

Ive tried other languages and guess what, Im using PLAYBASIC still.

Its the best forum for backup and help!

So KEEP ON CHIPPING AND IMPROVING PERFORMANCE.

kind regards BAGGEY
