| More Details on X800 Hotfix for Tiger Pro Apps, Games |
| Although it's still not posted yet as of Tuesday afternoon (should be within 24hrs I'm told), I asked Chris Bentley (ATI Mac programmer) for specific details on the X800 Hotfix/update for Tiger Pro apps users (and some specific games) and why there was an impact on Doom3 performance.
"
Hi Mike,
There are four 3D bugs fixed in the hot-fix:
1) multipaned z corruption in Pro apps (Motion, Maya, Modo, Lightwave, etc...) The fix for this had no performance impact
2) occasional checkerboard textures in X2: Threat
The fix for this had no performance impact
3) wrong values returned from GetBeamPosition()
The fix for this had no performance impact
4) blocky z corruption in Sims 2: Rush Hour
The fix for this ended up causing a slow down in DOOM 3. (Mostly at high res.) We had to prioritize running correctly over performance. We'll work on regaining the DOOM 3 perf in an upcoming driver.
People who are just running DOOM 3 and haven't been effected by the other bugs, can stick with their current drivers and keep the slightly higher DOOM 3 perf.

(NOTE - on Wednesday the Hotfix was posted at http://www2.ati.com/drivers/ati_x800xt_hotfix_june05.dmg. I went to support.ati.com (cookies required) to get a link to the readme file/release notes which mirror the info posted here in Monday's news.
(FYI - I've updated the earlier post/request for PL Z-Force card switch settings to include a link to a scan of the setttings page from the manual. Also updated Other Net News listing for article links and a few software updates.)

| First Feedback on Mac X800 XT ROM 109 Update |
| (The first reader mails on the X800 XT 109 ROM update mentioned in yesterday's news.)
"
Greetings, Mike. I installed the v109 firmware on my system (Dual 2GHz G5, 30" Cinema Display/23" Cinema Display ADC) in Safe Boot mode. On restart, random speckles appeared on the 30" display (none on the 23"). A lot. So I did a PMU reset (unplugging the power cord), waited a few minutes, then restarted zapping the PRAM and then doing the NVRAM reset in open firmware. (see FAQ's G5 section for how-to.) Now both screens are perfect. Not sure which step(s) did the trick.
First thing I noticed is that it cured the problem with Doom 3 where it
wouldn't run in full screen. (30in Display used.) This developed with the 108 firmware update. (Odd - as I didn't see this problem here with my Sony CRT. Firmware 108 ran Doom3 full screen OK (tested at 1024x768 and 1600x1200-Mike) Now it plays fine in full screen, and frame rates seem to have improved, although I've only had a few minutes running time on it.
(he later wrote with more info on the doom3/full screen issue)
I forgot to specify that I'm running Tiger 10.4.1... Anyway, I run Doom 3 at 1600x1200 and full screen on the Apple 30" means having the black bars left and right.
With firmware 108, the Doom 3 screen was just that - 1600x1200, pixel for pixel, on the center of the screen, with black all around it. (i.e. not stretched to the full 30in display screen size.) I tried other resolutions, and the frame took on the corresponding one-to-one size on the monitor screen. Now with firmware 109, all resolutions run at full screen, and it's nice that I can play the game at a lower resolution, resulting in better frame rates, still at full screen.
The artifacts (speckles) on the screen never reappeared. Altogether, firmware rev. 109 is a totally positive update for me.
Apple System Profiler shows ROM revision as 113-A35801-109. I was also surprised to see that the DMG file of the installer was automatically moved to the trash after the restart.

The notes on the Hotfix (separate update for Tiger Pro apps users) mentioned a performance impact for Doom3 at hi-res w/FSAA but as of this morning I still can find a page/download for it. (See yesterday's post for info on the hotfix to address issues some Pro Apps users reported in the past.)
"
Updated my X800XT to firmware 108 to Firmware 109 Mac OS 10.3.9 Dual 2.0 G5 (2004) 2.5 gigs ram.
I had no problem with firmware 108 and the fans were quiet, now my fans are high pitched and spinning much faster, I am going to try to go back to 108. I don*t think it is just the fan on the ATI, I think both my front processor fans are spinning much faster now I used to be able to see them spinning now they are running too fast for me to se the blades.

(Not sure why the update would have affected the system fans but I asked if he tried resetting the NVRAM, Toggling Energy Saver performance settings, etc..) Anyone else notice higher fan speeds after the update?
I welcome other X800 user feedback on the update. (Include your OS version, previous rom version, etc. in reports. Thanks.)

| Note to owners of older 22in Cinema Displays (check rear support leg) |
| I don't remember any other reports of this but posting as a FYI to anyone else that has a very old Cinema Display.
"
hi mike,
i have some sad news. about 5+/- years ago i purchased a new
22" apple cinema display, from apple, took it out of the box,
and put it on my workstation desk.
it has never been moved or touched, since then, except to gently
wipe the screen with the supplied cloth.
about a half hour ago, i'm sitting here working, hear a cracking
noise, and watch my cinema display fall over on it's back.
the plastic 'fold out' (leg/stand) in the back absolutely broke off below the screws that hold it to the case and a jagged break on the plastic is present.
if you want pictures, let me know, and cinema display owners be
aware. (sigh) i guess i will have to mount it on an artist easel.
best2u, curtis

Since it sounds like the "leg" broke (i.e. no damage to the rear cover/mtg area) I asked if he'd tried calling an Apple parts dealer to see if he could order a replacement. I have an original Apple DVI 22in Cinema Display and haven't had a problem with the rear support stand yet. (But it's been packed up since the move last fall though so I'm going to dig it out to check to see if there are any evidence of cracks on the support "leg".)
UPDATE: Wednesday's news page had another reader report of the support foot/leg breaking and included a link to a source for the Cinema Display (DVI/ADC) Foot (P/N 922-394) that has a price of $40 listed (as of 6/15/2005). |

(If you post an updated entry - make sure you use the same name, etc. as you did before so I can find your past entry. Thanks.)
(Incomplete entries are deleted. Do not post questions in the database, it's for drive reports not questions on what drive to buy - for that try searching the database for reports from owners of your mac model on the drive type/brand/interface, etc. you're interested in.)
