I noticed that NVidia is starting to put out pixel shader 4 cards. I wonder if the bug will still be in those. I guess only time will tell. I saw that Agnari speculated that the GTX 250 series is affected. Has there been confirmation?

Edit: I see that Aerkgon said the GTX 280 is bugged. Damn!

The biggest kick in the butt about all of this is, to us its a "bug". It might not actually be a bug. It could be that Turbines code is using some feature of Hardware TnL in a nonstandard way. The problem is a few other games did the same thing, everyone else who uses 3dAnalyze become examples. Nvidia might have written a strict Hardware TnL emulator when they moved it to the shader engine, and left out some of the commands other people were still using. Since nearly all of the "bugged" games are in gaming terms ancient, they might have assumed no one would use that feature set any more.

Turbine won't give us any clue about how the sky is rendered, somedays I wonder if anyone on staff actually knows.
The voodoo that is Nvidia isn't about to reveal the codebase for Hardware TnL and the shader based "Hardware TnL".
This would be so much easier if we could have a list of what Hardware TnL did and that the shader TnL does. Just 1 by 1 go thru the features till we find the 1 piece thats missing...

I so wanna slap both sides somedays...

Or cares.

I hate to say it, but I've lost a lot of faith in Turbine over this issue. They've known about the issue forever. They've known the issue is hardware T'n'L for months now, and they haven't said squat. Although it doesn't "break" the game, I think will keep new and old players away. An update on the status of the fix, or if there is going to be a fix would be a nice gesture.

Fyrie - I had pointed this out in my first post over on http://acforsaken.com/

Even if that update is we dunno anything new, its more tolerable than the silence.

blah

have you checked out V-I's thread on a software fix to the skybox bug here on the utilities board?

Wubbie,

I just saw Blendarus' post on the official boards about running the two cards at once. That's funny. The beauty of it is that they both use the same unified driver. That puts even more suspicion on the actual on-chip implementation. That being said, I still firmly believe it's a Turbine fix. They are doing something funky. Most of the compatibility issues with Nvidia are widespread and well known. This is the only time I've ever seen this bug.

On a related note, I just got a CRT monitor, so I may come back using my 6000 series card since playing in my LCDs native resolution won't be an issue any more.

Well there is the other option I am chasing in my mind that the sky textures got updated.

I keep having "issues" around new textures even with my 6600's...

Series 8 unified the Hardware TnL into a software on board thingy

But on a Series 6 I can reproduce a "similar" glitch

Hurm when i get time I should load up VI's fix for my machine and see if my lightpost is still flipping out...

Are there any screenshots or video of this other glitch floating around?

I had gathered all of the screenies I encountered, and someone has sent me a link to a video once.
I might still have them but have to dig thru about 4 TB to find them...
There were some screenies in the Nvidia thread someone linked to earlier...

I keep looking

edited bit -
Fyrie - check PMs...

The texture tearing (someone elses term) on the light post is VERY similar to the skyflicker, just in a much more constrained spot with darker texture.

So I asked over on the ac boards and a series 8 user said they to had the post shimmer...
and then I was pondering...

"See what boggles my mind about this is I run Series 6, No Skyboxen but I do get the Post shimmer.

I wonder if someone updated a sky texture, blue clouds whatever, and thats whats causing the flip out...

Replacing a bugged texture with a nonbugged one would be...

hurm...

Its way beyond my tech level, but once upon a time people were able to pull textures from the dat files... and in some cases replace them... but I think all of that got abandoned pre TOD....

So we woudl need -
- the ability to "hack" the .dat file (stop looking at me like that Turbine employee)
- Which texture is used for Sanamar Lamp posts to know which one to change

I'd settle for them to be candy canes at this point. But a known "old school" texture used in replacement and the shimmer stopping means the actual fix is a simple texture replacement.

A successful result would be a proof of concept... and that means it SHOULD be in the next patch...

Now to figure out how to make this happen...."

This is WAY outside of my scope, and the people will the skills are prolly busy on other things...
but I live in hope
