Overall File tearing and artifacts?

[Portal]

So when you " rebild " what all do you do ?

Take the whole machine apart - check all the card serial numbers (make sure they are ours...) blow out all the dust - clean the fans, clean the case. Re-install cards, wipe content drive. in cases where other software has been installed. I wipe the system drive and re-install from a disk image I've created - it has the best optimised settings, and all relevant software and drivers installed etc. Output panels and scan converters etc usually need checking and some re-wiring

Now that V4 is comming along - I'm starting to build dual partition so still got option of either version (once v4 is properly released)

Then soak test it all for about 4 hours and check al outputs. Its a bit of a long process - but some of it gets done when the catalysts come back off jobs - so that theres a quick turn around when they go back out...

for file tearing try v3.31

this was caused by apple changing a graphics algorithm after 10.3.5

[Portal]

So preferred versions are v3.31 running osx 10.3.5 ???

Unfortunately 3.31 is still tearing. I just gave it a major workout on 10.3.9 and it still tears.

Haven't tried 10.3.3 + 3.31 yet but 3.3 is stable on 10.3.3.

My systems use dedicated OS X drives which I reformat on a regular basis and I am pretty religious about only having a basic install on these. I use external SATA RAIDS and have a second disk in the machine which I use to boot from if I need to edit onsite or use the G5 for something els.

If you still have an 'old' style G5 and are lucky enough to be able to run 10.3.3 with all relevant updates - this is the most stable solution for V3.3 G21. However, If you have a 'newer' G5 which came with Tiger installed - you wont be able to downgrade back to 10.3.3 - so in this case - 10.3.9 with all relevant updates and V3.3 G21 is most stable. However, you will have to select 'slow disks' to get arround issues of catalyst crashing. (an open GL bug - i've been told....)

As for a stable platform to run v3.31 - in theory - the answer is 10.3.9 with all relevant updates and up to date ATI drivers etc. However, I havent had a chance to fully test this yet.... So I'll be sticking to 10.3.3 + V3.3 G21 until I can prove that v3.31 is show worthy and stable on 10.3.9. At the moment we're staying away from tiger...

you dont want to use 'slow disc' mode in 3.31 it kills performance. ( and in 3.3 )
it was a driver sync bug when a new movie loaded. related to other changes around 10.3.5

it is fixed in 3.31

it gets to be show worthy by people using it and reporting problems....apart from that there is no magic wand i can wave.

having to deal with the mulititude of endless hardware and software changes from apple the last year has been just about impossible.

this is an open platform - not fixed like a lighting console.
end users can install their own software and hardware.

there is no way that any more than a small number of configurations can ever be tested.

[Mr_P]

The sooner a 'BASE' configuration is quoted - the better...

It IS possible to have a basic configuration to use as a base for testing and development. There are FEW options involved when you look at the HW/SW spec

Agreed - there are the 'newer' and 'older' 2G G5's the latter will run 10.0.3, the former will not (10.3.9) Heres a spec most people dont deviate from:

Dual 2G Mac
OS 10.3.3 (or 10.3.9)
512MB Ram
SATA System HD
SCSI Content Drive
ATTO SCSI Controller
ATI 9800 SE 256MB
USB card (with internal port for dongle)
Miglia Alchemy Capture Card - or Blackmagic SDI capture Card
optional Keyspan USB adaptor

Software: Nothing other than the OS loaded + updates + catalyst.
ATI drivers + control panel
Atto dirvers
Keyspan drivers
Black magic or alchemy drivers
re-namer program (Renamer4Mac)
(VNC software - tech only - OSXvnc + Chicken of the VNC)


Its a pretty simple spec.
Hire companies dont send out machines with other software on..... (what the users put on is down to them - hence why they get wiped when returned.)

Most designers use their own Macs / laptops for editing and content creation - so dont tend to install any software on the servers - (apart from OSXvnc for network access, only when needed)

SO - hardware spec is pretty simple, software spec is simple... Its a basic spec that everyone uses... why not use it as a minimum spec and benchmark for testing?

there are different kinds of tearing....one of them is called vsync off and is a feature used by graphics cards manufactureres so that they can get the headline frame rate up in games applications.

if you have setup the ati displays control panel to use a custom application profile. then you need to have 'vertical sync' set to ON.
