CCP:

Aany idea when you might be able to sort out the nasty Z-buffer issues that people are experiencing?

I think this is mainly an issue with Nvidia cards - but if Radeon and other owners could reply then we can get an idea of the scale of the problem...

Stations look AWFUL as you are aproaching them, with "shimmering" polygons edges where two objects intersect at slight angles, and certain roid fields look EVEN worse - I've had roids half vanishing inside other roids as I pan the view....{very freaky)

Surely this must be pretty easy to fix?..

BTW - my card is a GF4Ti4200 using latest WHQL drivers....

Yes!! Please fix that...
I had the problem with my GeForce 2 mx before, but I though it was due to the card...
Moved to a GeForce 4 ti 4200 @128Mb and the problem is still there :(

This was also an issue in World War II Online, they fixed it, so I know it can be done.

I did a quick search about WWIIOL and the Z-buffer fix, I might play around with the Z-buffer settings, and the 16/32 bit settings, of my video tonight to see if it makes a difference.

I haven't got a single link. rather I was glancing through all the google results to see stuff to jog my memory.

I've moved from Windows 98SE to XP since and upgraded my video card twice as well, so I'll have to see the new video properties dialog before I can comment further.

Okay I have this link that mentions the video setups, thus:

As for Color Bit, there is a graphic fix in version 1.50 now that stopped the Z-Buffer sorting of graphics. Before the fix, as stated before there was a sawtooth banding on cards runnig at 16 bit color. The fix requires that cards run with 32 bit color. This will cause a drop in FPS from runing in 16 but the fix seems to be worth it. Some ATI cards are reporting that even when runing in 32 color, they are still seeing banding. This is being looked at by CRS.

So maybe CCP need to invoke mandatory 32-bit Z-buffering ?

Initial research, basically that the nVidia drivers I have for XP no longer have the Z-buffer options on them, so I can only assume it is 32-bit precision only.

Also, EVE is DirectX 9.0, I think that may allow greater control.

What is interesting is I decided to put Antialiasing right up to max (4.5 on my card) and the game looks a bit more sharpish and the "sawtooth" effect seems to be much less.

FYI: CPU; AMD 1.3Ghz, RAM; 512MB PC2100, Mobo; Abit KR7A (KT266A chipset), Video; GeForce4 Ti4200 128MB

BTW can a moderator move this into the "System Analysis" forum so it doesn't get bumped off into oblivion ?

The only reason you would see z-buffer artefacts at 24-bit precision (8 bits are stencil) is if they have the front clip plane set too close to the camera.

Anti aliasing does help a lot, ive looked at this myself in beta.

problem with anti aliasing being enabled is that the texel alignment goes out of whack for most people, and using the Graphics driver and game alignment tools you can only get SOME of the text to look readable again.

it would be great if someone could find a fix for the saw toothing because it really is ugly as sin.

nice work xane.

I have same effect on my Radeon 9700 pro, shimering textures on stations, the worst being minmatar stations. Been like that since early beta/alpha.

The NVIDIA drivers used to have an option for buffer settings but, they are gone. the GeForce cards can use 16 and 24 bit but not 32 bit. That is the reason for the ugly station textures, no way to fix with current drivers, the ability to even unlock that area of the driver is not there anymore.

FSAA helps but I get strange screen flashes in the game when using FSAA on any setting other then 8x (software FSAA). When on 8x the text is unreadable. Unless I tweak the GeForce Texel Align settings.

SO I leave Aniso on 8x and leave FSAA off, bummer becuase it looks so much better with it on 4x FSAA.
