D3dptch1.zip

d3dptch1.zip (sometimes named d3dptch15b.zip) is the filename of the Direct3D "beta 1.5" patch for Carnivores. This patch was released on September 11, 2000, almost two years after the last Carnivores patch, carn1_3b.zip. This patch updated the D3D renderer to fix problems with the sky on some graphics cards and included the updated versions of Tyrannosaurus and the shotgun from carn1_3b.zip. The RELNOTES.TXT file included in this patch was identical to RELNOTES.TXT from carn1_3b.zip, except for  in the first line being changed to , and the addition of the line   after the list of graphics cards.

While this patch was developed for Carnivores, at least one person claims to have successfully used it for Carnivores 2.

RELNOTES.TXT
Carnivores Direct3D patch (beta 1.5) release notes

This patch works only with FULL version of Carnivores. This version of D3D patch was tested and worked well on the following chipsets:

Matrox G200 Riva 128 Riva TNT ATI 3D Rage Pro S3 Savage 3D 3D Labs Permedia 2

It also fixes problem with sky on some cards.

However, if you experience any problems with this patch, please download and install the latest drivers for your chipset. In most cases this helps. If you still have technical problems contact oleg@af.kiev.ua

There are three options that influence the rendering process.

1. COLORKEY (COLOR/ALPHA CHANNEL, default setting: Color) Some of the boards do not support colorkeying; this causes the appearance of black pixels instead of transparency. If you have this problem, please set this option to ALPHA CHANNEL mode. Some video boards can support both options, but setting this option to a specific mode can enhance rendering quality.

We recomend to set ALPHA CHANNEL on Riva TNT based accelerators.

2. TEXTURES (LOW/HIGH/AUTO) This option defines the size of textures used when rendering. If you have a video card with 8+ Megs of VRAM set it to HIGH or AUTO. If you have less than 6 Megs of VRAM it is recommended to set this option to LOW or AUTO (this will improve game speed). If you are not sure about the amount of video memory of your card, set it to AUTO(in this case the game will set the quality of textures depending on the amount of memory available and scene complexity).

3. FOG (ON/OFF) Usually, enabling fog will just decrease performance about 15-20%. But sometimes enabling or disabling fog can enhance or make worth rendering quality.
