[Fixed] Odd Differences Between Speed and Quality Settings.

I've noticed some bothersome differences between speed and quality settings.

Could you send me the map so that I can take a look myself?

Can you recommend a place I can upload this, and PM you the link? Otherwise I would need to email it to you, the compressed file is ~6 MB.

No problem. My mail account can handle that amount of data.

Sent. The area you want to see is directly east of the player start roughly 4992,-3136 and the tag is 52. The control sector is lined up with the display sector, and none of the 3d floors pass through one another. The control sector is at roughly 4992,-6272.

While standing on the low end of the 3d floor, I noticed I was pushed towards the high end. You may also want to have a look at the area further east (you'll have to fly there in game play) where you should be able to see some textures displaying at strange scaling intervals. I have no idea what that's all about, it's happening to a regular doom2 texture, not one of my hires textures, though I've seen it happen to hires textures before. 7312,-2896.

[edit] It's Map02.

The bug doesn't show for me so I don't know what to do about it...

Speed mode it shall be then...

What type of graphics card do you have?

I get this too, and yep, it must be another ATI thing. I've had it occur sporadically on a sloped 3d floor that I haven't touched in quite some time. One day it will be screwed up, the next few days, it will appear fine (although it appears messed up the majority of the time).

Maybe it's related to this 'bug': http://forum.drdteam.org/viewtopic.php?t=1500
Edit: I just tested out the 3d floor as a non-sloped variety, and the area that was skewed on the sloped version has the wrongly scaled texture. So it does seem the above link and this problem are related.

That one was merely an incorrect texture coordinate and not ATI related. But I can't reproduce this one here with none of the last 3 versions.

Maybe a different screenshot will help? Can't be easy to troubleshoot something you can't look at on your own computer.

It usually doesn't occur as extreme as it's shown in the screenshot. I found that the position of the vertices in front of it have an effect. If I remove the cut-corners from the floor pattern, the 3d floor slopes properly. It might be a bit hard to see, but the cut-off points for the slope are at the inner vertices of the inner square.

No idea if that helps. Cutting certain corners of the floor design change how extreme it occurs, if at all. I can get more screenshots with different degrees and different corners cut if it helps to show where the problem is happening.

I'm on a ATI 9600xt, just in case you ask.

Can you send me that map? I want to see that for myself. This gives me an idea about what is happening but I need something to reproduce it in the debugger.

Sure, I attached the map.

Post by **Graf Zahl** » Wed Apr 12, 2006 16:39

Yes, that's definitely screwed up. It looks like the z-coordinates are taken from the start of the linedef, not the current seg.

Fixed.
