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.
