Upgraded Video Card and now stutter fest

[Akula]

Hello

I upgraded my vid card from a Nvidia 8800 Ultra to a ATI 5850 Toxic.

Problem is now SH5 is stuttering noticable all over the place.

The game was silk smooth with my previous card, so I am at a loss to why a more powerful card should struggle...

Other games are running as I expect.

Is there a known issue with ATI and SH5? Oh I am using the 10.3 Cat drivers.

Any help would be greatly appreciated.

Thanks,
G

After updating my drivers to 10.3 I noticed the same stuttering.

All I have done so far is turn antialising off and seems to work, but other than that I have no idea mate...

[kylania]

You installed a card that's called "Toxic", what do you expect?

Tried turning off VSync? Made sure you installed the DirectX off the game disc? Turning of AA will help, but with a ridiculous card like that, you should be able to have that and shadows on and not even skip a frame.

it must be driver related. i have a q6600 with a cheap little 4600 series and it runs flawlessly. a card like yours shouldn't be having any trouble

I think its the driver, I was running fine on my 5870 until 10.3 no I've got a slide show in the control room but everything else runs upwards of 110fps and beyond, but I come down that ladder and the control room sucks me into 20fps or so.... until I get thru the hatch on either side of the control room.

It has to be related to the drivers. If you updated them recently try to go back to the previous version maybe try couple of them back.

Anyway, considering my bad experience, why would you go from nVidia to ATI. That in my opinion is a huge step backward.

I had it bad with my 4870x2, turned off vsync and everything is smooth. I haven't noticed any tearing either.

Yeah I always thought nVidia was a little better than ATI, but I think the gap has narrowed and they're both pretty much the same today. I know some games prefer one over the other. Maybe SH5 prefers nVidia?

I think nVidia cards had alot more problems with SH5. Mostly to do with shadows. This is the first time I've heard of an ATI card with problems for SH5. but it sounds more like a driver prob.... roll back to previous driver and all should be fine again. I got an HD 4870 and i've not had any problems. using driver 9.12.

And as for which is better between ATI and nVidia....... I'm an ATI gamer myself. But it's always been a close race and they often swap the lead, It's ATI in the lead ATM with the Radeon 5870 (fastest card on the market ATM)..... And yes some games sometimes prefer one over the other.

NVidia has slipped behind ATi in the past two-three years. Drivers support is also much better with ATi than Nvidia. They have monthly official (WHQL) releases for the past 5-6 years. Their driver team is also very responsive.

I don't know if SH5 is a TWIMTBP title, but Nvidia has been caught red handed providing support or other "incentives" to the developers, so that their game would run slower on ATi hardware or with missing features.

Basically, when NVidia produce a solid architecture like it has been the Geforce4 or the recent series 8000 they stick to the rules, otherwise, they'll resort to dirty marketing techniques, cheating in games, driver that will lower rendering quality, games "dis-optimized" for the competitors.

There's lot of firms in the IT area which should learn the meaning of business integrity.

Like Kylania said, try with V-Sync Off and restart the game.

I use a 4870 here and experienced high stutter when rotating the view with the mouse turn V-Sync Off fixed the problem.
When panning with keyboard no problem at all, strange...
Mouse problem or video driver problem ?

Using Logitech MX Revolution by the way, yours ?

[BigBANGtheory]

I had this problem last year when I moved from an Nv 8800 to an Ati 4890 on Vista.

I tried lots of things and I hate to say this but the only thing that fixed it for me was a clean OS install of Win7.

The only rational explanation I could think of was an Nvidia driver or codec somewhere that did not get removed in the uninstall and upgrade process, perhaps it wasnt registered correctly with Vista.

2 things you can do

1) Turn off Vsync
2) Reinstall OS. Windows has NEVER been found of changing the video drivers.

[Defiance]

Hiya's,

In game options i have to turn off V-Sync

I have AA on max (furthest right)

3D clouds i find drop fps so mainly have these un-checked

Shadows Off (think the fps drop is a bug to be fixed ? )

Light shafts off (my preference)

Windowed mode Off

Running 4890 xfire (no xfire due to game bug to be fixed) @ 1920x1200 Q6600 @ 3.6ghz and 8gig Mem in Vista x64 (sh5 installed direct to C:

Now as for driver options ...............

I have tried leaked/official and Preview

At the moment i am on Preview 10.4a off ati's site

Settings thus far in CCC are .................

AA - use app settings
Af x4 - (i'm still messing with this setting)
Cat AI - Disabled
Mipmap - High Quality
Wait for vert refresh - Off unless app specifies
Adaptive AA - Off
Triple Buffering - Off

So many variations but these for now until high fps rate killing mouse movement bug is fixed and hopefully the lack of xfire due to v-sync problems

Maybe use the above settings as a "ballpark" to get your card running smooth

Hope this might help you and maybe others

added ............ for ati

Ohh i have used driver cleaners with no ill-effects but some report problems, so just use ctrl panel remove options in windose, and install driver

Some leaked/beta ati drivers won't fully install unless previous drivers were removed, BUT, as a whole ati drivers are over-the-top-install, meaning say you have official 10.2 you just install 10.3 without having to remove 10.2 driver, if a new driver seems to install in under 20secs you can bet you need to remove previous driver first or you'll never get a fully working driver/ccc

5870HD here;

Had stuttering until I turned vsync off. Runs great however I do still have frequent mouse issues in first person view but not in external camera view. It will "catch" or change sensitivity. I don't know if it's video related or not.
