Darker polygons when running Tomb Raider with Glide

Hi,

I tried to run Tomb Raider with openglide by following the tutorial here: Tutorial: dosbox with Glide under Linux
Now, that tutorial is outdated, as it was intended for version 0.73, but I made it work for version 0.74 by downloading and building the current version of dosbox and openglide, and using the latest dosbox_glide.diff patch.

My framerate is now at a 30 fps constant so I'm quite happy with it, but I have some artifacts, as you can see below: some polygons are darker (or lighter) than they should be:

Here's my log when starting the game:

LD_LIBRARY_PATH=/usr/local/lib dosbox -conf dosboxTRLinux.conf 
DOSBox version SVN
Copyright 2002-2018 DOSBox Team, published under GNU GPL.

CONFIG:Loading primary settings from config file dosboxTRLinux.conf
"hardware2x" is not a valid value for variable: type.
It might now be reset to the default value: normal2x
MIXER: Got different values from SDL: freq 44100, blocksize 512
ALSA:Can't subscribe to MIDI port (65:0) nor (17:0)
MIDI: Opened device:none
Glide:LFB access: read-write
DOSBox has switched to max cycles, because of the setting: cycles=auto.
If the game runs too fast, try a fixed cycles amount in DOSBox's options.
Glide:Activated
Glide:Detected incompatible guest ovl/dll!
Glide:Resolution:640x480, LFB at 0x60000000 (physical) / 0x60000000 (linear)

I use a computer with an embedded sound chip and an ATI Polaris graphics card.
I'm on Debian unstable.
The game is The Steam version of the game.
The problem is always reproducible.
I use output=opengl and glide=true on the dosboxTRLinux.conf file, just like Steam configures it.
I haven't read the README, because I don't know where to find it 🙁

Now, I'm not really sure what I could change or what information I could provide, I'll take any help 😀
Thx for your time.

Use output=surface.

Thx for the tip. That got rid of the artifacts on the circular menu, but as soon as I try to enter the manor or start the game the game crashes with a segfault:

Here is my full dosbox.conf file:

[sdl]
#       fullscreen: Start dosbox directly in fullscreen. (Press ALT-Enter to go back)
#       fulldouble: Use double buffering in fullscreen. It can reduce screen flickering, but it can also result in a slow DOSBox.
#   fullresolution: What resolution to use for fullscreen: original or fixed size (e.g. 1024x768).
#                     Using your monitor's native resolution with aspect=true might give the best results.
#                     If you end up with small window on a large screen, try an output different from surface.
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
#                     (output=surface does not!)
#           output: What video system to use for output.
#                   Possible values: surface, overlay, opengl, openglnb, openglhq, ddraw, direct3d.
#         autolock: Mouse will automatically lock, if you click on the screen. (Press CTRL-F10 to unlock)
#      sensitivity: Mouse sensitivity.
#      waitonerror: Wait before closing the console if dosbox has an error.
#         priority: Priority levels for dosbox. Second entry behind the comma is for when dosbox is not focused/minimized.
#                     pause is only valid for the second entry.
#                   Possible values: lowest, lower, normal, higher, highest, pause.
#       mapperfile: File used to load/save the key/event mappings from. Resetmapper only works with the defaul value.
#      pixelshader: Pixelshader program (effect file must be in Shaders subdirectory).
#     usescancodes: Avoid usage of symkeys, might not work on all operating systems.
#         overscan: Width of overscan border. (works if output=surface)

# vmemsize: Amount of video memory in megabytes.
#             The maximum resolution and color depth the svga_s3 will be able to display
#             is determined by this value.
#              0: 512k (800x600  at 256 colors)

#           For build engine games, use more memory than in the list above so it can
#           use triple buffering and thus won't flicker.
#           
# captures: Directory where things like wave, midi, screenshot get captured.
#  memsize: Amount of memory DOSBox has in megabytes.
#             This value is best left at its default to avoid problems with some games,
#             though few games might require a higher value.

# frameskip: How many frames DOSBox skips before drawing one.
#    aspect: Do aspect correction, if your output method doesn't support scaling this can slow things down!.
#  linewise: Draw the display line by line. Needed for certain special graphics effects in games and demos. Can be changed at runtime but will be put in effect at the next mode switch.

#            Possible values: auto, dynamic, normal, full, simple.
#   cputype: CPU Type used in emulation. auto emulates a 486 which tolerates Pentium instructions.
#            Possible values: auto, 386, 486, pentium, 386_prefetch.
#    cycles: Amount of instructions DOSBox tries to emulate each millisecond.
#            Setting this value too high results in sound dropouts and lags.
#            Cycles can be set in 3 ways:
#              'auto'          tries to guess what a game needs.
#                              It usually works, but can fail for certain games.
#              'fixed #number' will set a fixed amount of cycles. This is what you usually
#                              need if 'auto' fails (Example: fixed 4000).
#              'max'           will allocate as much cycles as your computer is able to
#                              handle.
#            Possible values: auto, fixed, max.

[mixer]
#    nosound: Enable silent mode, sound is still emulated though.
# swapstereo: Swaps the left and right stereo channels.
#       rate: Mixer sample rate, setting any device's rate higher than this will probably lower their sound quality.
#             Possible values: 44100, 48000, 32000, 22050, 16000, 11025, 8000, 49716.
#  blocksize: Mixer block size, larger blocks might help sound stuttering but sound will also be more lagged.
#             Possible values: 1024, 2048, 4096, 8192, 512, 256.

My build on Ubuntu is fine. I use SVN version and several different releases, for eg. r3868, r4095 and the recent r4160. My test machines are having either entry-level NVIDIA graphics or Intel HD series.
You may want to look at fixing the following warning message.
"Glide:Detected incompatible guest ovl/dll!"

You may also want to try getting DOSBox compiled with 3Dfx voodoo1 chip emulation. In that case, you do not need OpenGlide, but you need GLIDE2X.OVL from real 3Dfx Voodoo driver releases. This is slower than using OpenGlide, and it is even slower on Linux if you happened to compile DOSBox for x64 build. However, if you have a decent CPU, then it really does not matter, especially for desktop class CPU.

Thx for helping. Sorry to ask, but I'm a bit new to this and I feel unsure as to what I should do next.
When you talk about SVN build, you're talking about Dosbox right?
So what you'd do is compile this: https://sourceforge.net/p/dosbox/code-0/HEAD/tree/
using this patch: https://github.com/voyageur/openglide/blob/ma … sbox_glide.diff
with this version of openglide: cvs -z3 -d:pserver:anonymous@openglide.cvs.sourceforge.net:/cvsroot/openglide co -P openglide
Am I right?

About "Glide:Detected incompatible guest ovl/dll!", I have no idea how I could fix that, or where I should look. Could it be the GLIDE2X.OVL bundled with steam version of the game? Any help appreciated.

I didn't know about the 3Dfx stuff, thanks for letting me know, I'll try that next if I'm still stuck.

Thanks a lot, that fixed that particular issue, but I have another problem.
The video at the start of the game (with the snake in the desert) plays fine, but the ones that should play right before going to Lara's mansion or starting a game (after the circular menu) are just a black screen. I can hear the audio tho. Any idea?

Did you happen to use "output=opengl" or " output=openglnb" again? I think that was still a problem only on Linux when OpenGL switching context from OpenGlide back to DOSBox. It may also depend on the Linux OpenGL implementation on your GPU. Nothing wrong with the in-game video, if you happen to go into Lara's mansion twice, the video would only show on 1st time and black screen on the 2nd. I remember using "output=surface" should fix this.

If you still get segmentation fault after using "output=surface", then try the following fix in src/gui/sdlmain.cpp:
<< #define SETMODE_SAVES 1
>> #define SETMODE_SAVES 0

Alternately, you can check out my 2-in-1 patch which includes both 3Dfx Glide pass-through and voodoo1 chip emulation.
Tutorial: dosbox with Glide under Linux
It patches against r3858 but I guess it is still good for current SVN. If not, let me know I can give you an updated patch for current SVN.

Nothing wrong with the in-game video, if you happen to go into Lara's mansion twice, the video would only show on 1st time and black screen on the 2nd. I remember using "output=surface" should fix this.

I use opengl because its the only one that goes ingame, using any other option segfaults when leaving the circular menu.

Alternately, you can check out my 2-in-1 patch which includes both 3Dfx Glide pass-through and voodoo1 chip emulation.
Tutorial: dosbox with Glide under Linux
It patches against r3858 but I guess it is still good for current SVN. If not, let me know I can give you an updated patch for current SVN.

Tha a lot, really appreciate the support. I'll try this as soon as I can.
