Solved it though. Perhaps the other guys with x1600 difficulties should try this?

X1950xtx
No overdrive kick in when going into SH4.

Other 3d programs it starts up.

I have all settings maxed in overdrive (watercooling) and have never had problems.

disable osd in att..that will elimate some crashes..had to do that in other games,,GH

Yes but it was ONLY to check if your ATI card went into overdrive or not. Guess ppl cant be arsed.

Sorry to bump this but I think we need to narrow down the problem with ATI cards Overdrive and SHIV not working.

Could any further replies to this thread come with actual useful information except just "me too's"?

Post what ATI card you are running and what catalysts you are using, together with other RELEVANT system informaton (no, we don't need to know the number and size of fans, whether your air- or waterchill your cpu, the size of your screen etc).

Even better is if you have double checked with ATI Tray Tools' built-in OnScreen Display whether or not the 3d-clocks fire.

With my ATI X1900XT its 500/600 2d and 621/721 3d, and it doesnt activate on SHIV.

Thanks, but thats nothing to do with this thread. We are using ATT as a tool to monitor our clock speeds, which are supposed to change when going to 3D mode in late model ATI cards, but they arent.

Okay, posted earlier regarding my x1950XTX. Here is some more info.

Running Cat 7.1 with overdrive enabled and start at logon checked.
Both GPU and Mem sliders are maxed (695 & 1098). Stable due to water cooling. CoH and FEAR play great.

I loaded up ATT and sure enough the 3d clock did not kick in when playing SH4. Even before using ATT I figured something was wrong when I would leave the game then immediately check my GPU temp and it was only at around 40C.

I tried an experiment. Leaving the Overdrive settings as is I went into ATT and used its overclocking feature. I know some have said it's squirrley with the x1950XTX but I figured I'd try.

I matched (sort of) the OC values of 695 and 1098 (although ATT would only go uo to 900 on the memory) and hit apply. My screen became corrupted but fortunately the ATI recovery feature kicked in and the screen came back fine. Thing is is that the ATT overclock values remained. I thought once the ATI recovery kicked in it would reset/negate the values.

Anyway, I went into the Overdrive screen and bingo, it said I was running at 695/1098.

Okay, so I turn ATT OSD back on and head into SH4. Clocks held at 695/1098! Additionally, I knew it was OC'ing 'cuz my temp was now up to 56C. This did not happen before.

Basically, I'm using both ATT OC'ing and ATI's Overdrive at the same time and it's holding. One caveat is that in 2D mode the OC'ing is still present ... it does not use the Overdrive feature of lowering the clocks.

It was too late last night to give it a thorough shake-down so I'll do that tonight after work. At least the 1950XTX is now using all of its potential!

ok..i posted a pic over in the ubi sh4 room ...my x1950 pro 256 pcie is running in game @621/770 ..using atitray tools w/ati overdrive..an ingame screenie ..upper right corner under fps...http://i24.photobucket.com/albums/c4...-3-2007_13.jpg

Thanks bunkerratt. And crap >.< If some works but not all then how the heck are we going to find out what the problem is?

no prob man..your welcome...hope the rest of you can figure out what the glitch is on your systems...i'm not trying to start any probs just posted the screenie as visual proof that it in fact is working and running fine in game...

Just a note for Vista users:

The current Catalysts for Vista do not properly support the Overdrive speed switching under Vista. In fact, the speed switching caused a BSOD for me. Catalyst 7.3's are supposed to address this issue.

That said, I've got SHIV running just find under Vista. :D

How many times did you try it out? Mine was random.

Same problem : ati X1950XT with Catalyst 7.2 under WinXP Pro ... No overdrive kick in when going into SH4.

Hope there will be a patch or a new Catalyst's fix for that.

my overdrive wouldnt kick in when i first started the game, was'nt till i started playing with the slider's and resetting them ingame after that it started to work.. now its working all the time.

Bump, because I just got an X1950 Pro 512MB yesterday! :damn:

Btw, 7.3 drivers came out last night with various vista fixes.

Same problem here. No overdrive in SH4. Checked with Ati Tray Tools.
x1950xtx, Windows XP, Catalyst 7.3 :down:

I had the same issue - no 3D speeds with SHIV - in fact, I had no 3D speeds at all.

I am running a X1900XTX with WINXP SP2. I was running CAT 7.2.

To fix the issue I uninstalled the CATs and ran DriverCleaner. I then DL'd the latest Omega Drivers and installed. After I did this my 3D speeds were switching on for everything EXCEPT SHIV.

To get it to switch, I installed ATI Tools and forced it - but just for SHIV.

Sigh...

How can i force the 3D mode?

As an aside - I know a lot of people visit websites that claim to offer "Windows performance" tips, and present a list of services to disable (that you probably shouldn't, but they say you can).

Anyway, one of the services frequently recommended to remove is the "ATI hotkey poller". This is a TERRIBLE IDEA. This is the service that is responsible for switching between 2d and 3d mode for ATI cards.

(For my money, every one of those sites I've seen are bunk and offer 'free tips' just to drive advertising traffic. Windows isn't as bloated as they'd like you to believe, and stopping or uninstalling any of the standard services without good reason is usually a bad idea.)
