QuarkTex NG 1.0 beta
====================
QuarkTex NG gives AmigaOS in WinUAE hardware accelerated 3D: Warp3D,
StormMESA (agl.library) and MiniGL programs draw with the PC's graphics card
through OpenGL, instead of the emulated CPU drawing every pixel.
It is an independent continuation of QuarkTex, the 3D virtualization
solution Robert Konrad released in 2003 (driver/video/QuarkTex, last
version 0.53), under the same license, the GNU LGPL v3.
What is new since QuarkTex 0.53
-------------------------------
- Runs in 64-bit WinUAE as well (0.53 needed the 32-bit one).
- Commands go to the host in batches instead of one emulator call per
OpenGL function; Warp3D is drawn on the host with OpenGL 3.3.
- New minigl.library: MiniGL games such as Return to Castle Wolfenstein,
Jedi Knight II, OpenLara and Hurrican run on the host's OpenGL, with
multitexture, paletted textures and vertex arrays drawn by the host.
- Frames are written into the Amiga's RTG display memory, so the 3D picture
shows in a window, a full window and fullscreen, scaled and filtered by
WinUAE like any other Amiga graphics (0.53: windowed mode only).
- Stencil buffer, chroma keying, mipmaps and several 3D contexts at once.
- Fixed: black fog, wrong texture colours, ignored palettes and texture
updates, broken Z-buffer reads and writes, depth writes that could not be
turned off, leaked textures, W3D_Query answers.
Performance (Intel Iris Xe, 68040/68060 with JIT)
-------------------------------------------------
Warp3D, 1.2 million triangles QuarkTex 0.53 1.34 s, QuarkTex NG 0.39 s
RTCW at 640x480, no frame cap MiniGL Classic on Warp3D 157 fps,
QuarkTex NG minigl.library about 170 fps
RTCW, data per frame to host 1.37 MB before, 22 KB now
Requirements
------------
- Windows with a graphics card and driver for OpenGL 3.3.
- WinUAE (tested with 6.0.3 and the 6.x betas), 32-bit or 64-bit.
- AmigaOS 3.x, a 68020 or better with FPU (68040/68060 recommended),
Picasso96 with an RTG board (uaegfx).
Installation
------------
1. Copy the two files in WinUAE/ (quarktexng-windows-x86.dll and
quarktexng-windows-x86-64.dll) into your WinUAE directory, next to
winuae.exe and winuae64.exe.
2. Copy the three files in Libs/ (Warp3D.library, agl.library,
minigl.library) to LIBS: on your Amiga. Keep copies of the libraries you
replace. The libraries and the DLLs belong together.
3. Set up WinUAE as below.
WinUAE settings
---------------
Required:
- Settings, Host, Miscellaneous: "Allow native code" (native_code=true).
- Settings, Hardware, CPU and FPU: FPU "CPU internal" with the precision
"Host (80-bit)" (fpu_msvc_long_double=true). With the default 64-bit
emulation games compute values a real 68k FPU does not: in Jedi Knight II
the first person weapon never shows, in RTCW it disappears. The libraries
check this; minigl.library warns in a requester.
Recommended:
- CPU 68040 or 68060 at "Fastest possible".
- JIT on, cache size 16 MB (cachesize=16384), JIT "FPU support" on
(compfpu=true). The games themselves run on the emulated 68k: with the
JIT FPU off, Jedi Knight II fell from 90 to about 15 fps.
- RTG board UAE Zorro III, 64 MB or more (needed for fullscreen).
- Z3 Fast RAM, 256 MB or more for large games.
README.md in the archive explains every setting and has the full
performance tables.
Known issues
------------
- MiniGL Classic (the Warp3D based minigl.library) crashes in fullscreen on
QuarkTex NG's Warp3D.library. Use the minigl.library of this archive.
- On planar or 8-bit screens the 3D picture is drawn in a window of its own
over WinUAE, which shows only while WinUAE runs in a window.
- The rotating passport in OpenLara's menu draws dark.
