All I know is that this bug has made the game not enjoyable atm. Inevitably, the screen corrupts, I can't make out what is happening, and die. After three or four times a day, its begun to make me hate AC. I don't know how hard it is to fix, or if Turbine is aware of what is causing it why Nvidia just can't fix it.


If there is a work around you all can up with, that would be great. Especially if it did not involve some other OS or buying a new card.

Then you should follow this thread.

I don't have a series 8 card... But I've been building and poking at computers for over half my life. I have all sorts of ideas but without a Series 8 of my own that is known to do the bug I can't say what will and will not work unless someone takes one of my ideas tries it and reports what happens.


Current Idea is - Omega or NGO Optimized drivers. They are modified drivers that are tweaked for better gaming. If they make a FPS a little better they might fix whats wrong in AC.


Someone step up and try this..

Drivers don't void a warranty, shouldn't make it explode in flames, and you can always roll back.

Here's my workaround. I got an ATI card and it runs AC like a champ. Going to Ebay my 8800 GTS and it alone will cover about 2/3 of the cost. Also, the ATI card runs about 50% cooler. My room temp has dropped 10 to 15 degrees

Ok... I'll bite


Link me to these drivers. I'll reinstate my account.

I've tested the following drivers to no avail:

NVidia 171.23_beta_WinXP_32bit-[Guru3D.com]

nvidia_omega_xp2k_216921.exe

nvodngov116369.exe (tried both regular and compatibility install)


I also tried disabling combined writes, lowered acceleration to the lowest you can go and still have D3D accelerations, and I tried forced disabling of AA through the nvcontrol panel.

Fyrie - what happens when you turn off let the application decide for all the cool settings in the control panel...

Antialiasing, Anisotropic.. etc etc Lets see if this happens when all the settings are taken to the lowest and forced to be that way... Lets focus on 1 portion at a time. So lets reset the DirectX/Windows settings to their "default" position and focus on all the bells and whistles in the Nvidia Control Panel. I am doing this looking at the old fashioned one I run for my 6600's v93.71, yeah I know they are not the newest bestest ones but they work for me.


HURM... Classic NVIDIA Control Panel The user interface you are using right now. This interface is provided for legacy purposes only. All new features and enhancements are only applied to the new Nvidia Control Panel.


So what if we build one for acclient.exe and set everything to lowest or off and see...


If and thats a big if this finds the "shimmer" then it might be possible to locate the 1 or 2 offending settings and then make settings that keep the shimmer at bay for now.


http://downloads.guru3d.com/download.php?id=2

this is a list of all of the modified drivers they offer... wow thats alot...


bit i scavenged form their boards - "I have the 8800 gts 512, any drivers after and including the 169.21 has broken AA profiles. I'm using the 169.17 Beta which has FSAA profiles working. It doesn't support the 8800 gts 512 so you have to edit the inf to get it working."


I know this is a little jumbled, but I am high on cold medicince so alot of this is free form outta my brain I hope you can piece togeteher what I am saying...


But if its AA thats sporked in the newer drivers... then changing the setting wouldn;t matter... and if it was using the wrong stuff it might make things behave badly...


wubbie - i think i need more medicine...


editied bit...


Has anyone considered posting on 3dgurus and risking the noob flames to see what they think the problem might be?

I mean some of these people edit the drivers on code level, they might have better ideas than me... they might at least give an idea what settings might help in making it stop. I'd do it but I'm high on cold medicine and I can't do justice to the problem... but someone who has the problem and screen shots could probably get help...

Looking through the Guru 3d driver archive, 97.94 was the first official 8800 driver, however I was able to install 96.89, but nothing earlier than that. Therefore I am using

96.89 as the base. The bug does exist in 96.89.


Here is the baseline/default settings:


_Anistropic Filtering_

<Use global setting (application-controlled)>

Application Controlled

Off

2x

4x

8x

16x


_Antialiasing - Gamma correction_

<Use global setting (on)>

Off

On


_Antialiasing Mode_

<Use Global Setting (on)>

Application Controlled

Off

Enhance Application Setting

Override Application Setting


_Antialiasing Setting *Only Avail Depending on Above*_

<Use global setting (application-controlled)>

2x

4x

8x

8xq

16x

16xq


_Antialiasing - Transparency_

<Use Global Setting (off)>

Off

Multisampling

Supersampling


_Conformant Texture Clamp_

<Use Global Setting (Use Hardware)>

Off

Use OpenGL Specification

Use Hardware


_Error Reporting_

<Use Global Setting (Off)>

Off

On


_Extension Limit_

<Use Global Setting (Off)>

Off

On


_Force Mipmaps_

<Use Global Setting (none)>

None

Bilinear

Trilinear


_Multi-Diplay/mixed-GPU Acceleration_

<Use Global Setting (Multiple Display Performance)>

Single Display Performance Mode

Compatability Performance Mode

Multiple Display Performance Mode


_Texture Filtering - Anistropic Sample Optimization_

<Use Global setting (off)>

Off

On


_Texture Filtering - Negative LOD Bias_

<Use Global Setting (Allow)

Allow

Clamp


_Texture Filtering - Quality_

<Use Global Setting (Quality)>

High Quality

Quality

Performance

High Performance


_Texture Filtering - Trilinear Optimization_

<Use Global Setting On>

Off

On


_Threaded Optimization_

<Use Global Setting (Auto)>

Auto

Off

On


_Triple Buffering_

<Use Global Setting (On)>

Off

On


_Verticle Sync_

<Use Global Settings (Use 3d application settings)>

Use 3d Application Setting

Off

On


I have indicated the default selected settings by placing < > around the setting. I will try your suggestion of letting the application control everything that it can and turn everything else off. If you can think of specific settings based off of the above template, please let me know.

cooookie?


Fyrie - my original thought i think was to set everything to the "lowest" setting and then see if the bug was till there.

The gradually increase the settings until we foudn the trigger, hoping that its just 1 thing.


so whctah find


hurm hurm hurm??


did you find something that fixed it and now are playing away forgetting to let everyone else know how to fix this?


hurmmmmmmmmmmm?

Sorry.. False alarm. One of the annoying things about this bug is that even though on my system it usually surfaces within a minute of playing, on rare occasions it will take up to 15-20 minutes or so. There doesn't seem to be any rhyme or reason to when it takes longer to show up as it doesn't only happen when I try new settings.


Here is my current configuration:


Driver Version: 96.89 (97.02 is the first 8800 driver, but 96.89 is the oldest one that will actually install that I've found).


Settings:

_Anistropic Filtering_

Use global setting (application-controlled)

<Application Controlled>

Off

2x

4x

8x

16x


_Antialiasing - Gamma correction_

Use global setting (on)

<Off>

On


_Antialiasing Mode_

Use Global Setting (on)

<Application Controlled>

Off

Enhance Application Setting

Override Application Setting


_Antialiasing Setting *Only Avail Depending on Above*_

<Use global setting (application-controlled)>

2x

4x

8x

8xq

16x

16xq


_Antialiasing - Transparency_

Use Global Setting (off)

<Off>

Multisampling

_Conformant Texture Clamp_

Use Global Setting (Use Hardware)

There was something new that I noticed about the bug. As noted earilier, sometimes it flickers to white and sometimes it flicker to another sky texture. I did notice last night that when I was getting flickering to a cloudy sky texture, the texture seemed to be skewed the wrong direction. Also at one point at night the sky was the standard black sky with stars. I started to get flickering with red and green, then BAM, the Aurora Borealis overlay effect suddenly displayed across the whole sky (as I'm guessing it should have been doing before the flickering).
