Z Compression Mode

UnTouchAble · Aug 28, 2005, 02:06 PM

What does this do and what should i put this on for best performance?

On ATT it has 3 options, Default, 0 and 2.

It has to do with Z compression and I believe its more quality than speed but 2 would (I assume) be full compression, Default being a balance, and 0 being no compression.

UnTouchAble · Aug 28, 2005, 06:17 PM

So... 2 would be best performance?

H3X4D3C1M4L · Aug 28, 2005, 06:31 PM

I suppose so. I remember fiddling with it in Rage3D Tweak way back in the day but it didn't have a day/night performance difference.

Use default mode

UnTouchAble · Aug 28, 2005, 07:38 PM

Ok, what about Z Top Disable and Mip Map Filter?
Should these be ticked for performance?

More compression means more performance but it also sacrifices quality , if you are looking for performance select 2.Try and see

Edit:Yes what is Z Top Disable???

Default mode is best

We are working on them...you'll see them very soon

petri1 · Aug 29, 2005, 06:08 AM

aah music to my ears i´ll be waiting then and man are they gonna be pu to the test.
maybe not so much in 3dmark and so on but FEAR BF2 HL2 those are some good pointers on how the drivers perform hehehe

Z Top Disable - Similar to Disable HyperZ

UnTouchAble · Aug 29, 2005, 01:12 PM

So would it increase performance?

I don't think so , it must be related with Z comparison or Z compression algorithm.Maybe i am right or not.But i don't know exactly what it is

*Ray Adams* · Aug 29, 2005, 05:30 PM

No! It will not increase performance! It will disable HSR - Hidden Surface Removal or in other words HyperZ. Read about HyperZ on ATI's web site.

Z culling/filtering/occlussion/yadda yadda deals with the "masking" of unseen surfaces, thus not forcing the card to render what isn't seen.

Example: if there's a tree in front of a barn, with HyperZ enabled, it won't render the portion of the barn masked by the tree, thus IMPROVING performance. Disabling it forces it to render the proper faces of both the tree and the barn, adding more work to the stack and slowing the card down.
