ATI: Auto 2D/3D overdrive problem
 

As you may or not know. Modern ATI cards only run at full speed (core/memory/voltage) when running fullscreen 3D, compared to 2D desktop mode or windowed games where they underclock to stay cooler/quieter. This isnt usually an issue, unless you play lots of games in windowed mode (like i used to with my old Nvidia card). In my case 2D = 508/600 where 3D = 655/1008.

I noticed today on my x1950XTX, that on rare occasions while starting and playing SH4 the speed was still at its default 2D setting and hadnt bumped up the speed to fullscreen settings.

Im using ATI Tray tools OSD to monitor speed and temp. I thought i'd check because as you can imagine, this has quite a noticable effect on performance.

Im wondering if anyone else has noticed this? Cats 7.2 btw. With version 1.0 and 1.1 of SH4.

PS.. I reallllllly need some FSAA :P

I've heard about it but can't check it. Ive downloaded ATT. How do I enable it to show me current clockspeeds?

[edit]
My god! you are right! I am using X1900XT with Cat 7.2. There is now way I can get SH4 to fire up my 3d clocks (621/721 on X1900XT). IT stays at 500/600. If I fire up WoW it immediately swithces to 3d clocks.

I went into my CCC overdrive panel, enabled it, and then restored defaults, and clicked apply at startup. This seemed to work the next couple times (3) I loaded SH4. Though as i said, its random so ill be monitoring it.

I cant use the ATT overclocking because the support for x1950xtx is limited. Otherwise id make a profile to force it into the right clock speeds. :(

I dont know if the latest Nvidia cards work the same way. The last Nvidia poo i had was the 6600GT which I had manually set higher by default anyhow. :)

Forget about overclocking. Both Ati Tray Tools and ATI Tools makes your computer crash if you use their OC options with SHIV. Ive tried many different methods now and there is just NO WAY you can run SHIV at its intended speed on a X1900XT with Catalyst 7.2.

The 1.1 patch does not fix this, unfortunately.

I dont mean overclocking as such, i mean using the overclocking settings to set the default clock speeds. (Btw, Driver level, not low level).

Anyway im not overclocking, i've just enabled overdrive (in CCC not ATT) and left it default speeds, which seems to have fixed it for now. A few more game starts will tell.

All im using ATT for is the OSD.

?my ati x1950 pro clocks and stays clocked usin ccc and overdrive..no probs at all

Makes no difference. I've been there.

Yup, same problem here with my X1950XT and Cat 6.12. Not good... :hmm:

Same problem with 1.1 unfortunately

I have a ATI 1600 and just installed lastest drivers and I am running at my desktop at 1280x960 and SH4 is running very slow.I can not figure out why as I have a P4 3.2 with 2 gigs of ram also.

Same here. P4 3.0 with 4 gigs ram. ATI x1600 512 meg video. Even FSX runs better and that's not saying much. Has anyone tried the Omega drivers? I might give that a go this weekend.

Please all of you be so kind and post on the UBI forums too. Not sure if its Ubi or DAAMIT that are responsible, but attention to the matter would be nice.

I use the Omegadriver based on 6.12, doesn´t help.

The devs monitor Subsim as well.

Thanks Gizzmoe. You most likely save me grief. Swaping vid drivers has brought me down a few times in my life.

Maybe problem with the way the actual 3D is being handled by game engine in contrast to the 2D interface, ie. the rescaling stuff of fixed res, so driver doesn't get the hint that, "underneath" the 2D interface a 3D app is running as well?

Good.

To all of you with ATI cards that suspects something is amiss. I suggest you install ATI Tray Tools.

Start the program and answer no to the popup. YOu want the ATI "Hotkey Poller" running so that the 3d mode "Overdrive" clock function still works.


Right click the Ati Tray Tools icon in your system tray,

Tools & Options -> OnScreen Display
Select the tab FlashOSD.

Select the "Show all time" from the drop down boax and tick the boxes for GPU speed and Memory Speed.

Click OK.

Now you should see information about gpu and memory speed for your ATI card as soon as you run a 3d-program or other DirectDraw application. When I launch a "proper" 3d-game I see my clock go from 500/600 to 621/721. Thats good.

When I launch SHIV it stays at 500/600.

Please do this and post your findings here. Include what OS you run and what version of ATI Catalyst you use.

like this:

OS, ATI card, catalyst driver. CPU, Mem.
2d clock speed ???/???
3d clock speed ???/???
SHIV clock speed.

Windosx XP SP2, ATI X1900XT, Catalyst 6.12. Also tested with 7.2.
AMD X2 4400+ (2 core cpu). 2048 MB memory. Have AMD and MS hotfix KB896256 for dualcore cpu installed.
2d clock speed 499/599
3d clock speed 621/721
SHIV 1.0/1.1 clock speed 499/599

Hmm... I'm starting to get worried here. I also have the ATI x1600 pro (AGP) 512mb and I'm getting 17 fps on the bridge at 1024x768. :shifty: All graphics boxes selected OFF. Never had a problem with SHIII. Ran at 35-45 no matter what.

Other specs:
AMD 64 3500+ 2,21mhz
1Gb Ram

...mebbe because the x1600 doesnt support Overdrive? . . .
