Quake 2 OpenGL ES 1.0 renderer, for any Pi model, 60+ FPS

Sun Jul 28, 2024 10:47 pm

This has been asked for years, and I've suceeded in making it:
https://github.com/yquake2/yquake2
(Original pull request: https://github.com/yquake2/yquake2/pull/1128)

To see how it looks: https://youtu.be/eeijJNQFGKo
This reaches 71 fps at 1920x1080 resolution in a Raspberry Pi 3 B+, using Raspbian Buster, when running timedemo 1 and map demo1.dm2.

If you have compiled Yamagi previously, you are ready to go. If you don't, you'll need some packages:

Code: Select all

apt install build-essential libgl1-mesa-dev libsdl2-dev libopenal-dev libcurl4-openssl-dev

Then, change to the cloned repo (master branch) and run:

Code: Select all

make with_gles1

Files appear in the release directory. To use the GLES1 renderer, run the game with:

Code: Select all

./quake2 +set vid_renderer gles1

Other OSs may not support GLES1, but if they support GL1, they can use the new gl1_lightmapcopies cvar to improve performance. Just pull down the game's console, type gl1_lightmapcopies 1 and restart the game.

Instructions for RetroPie (automatic compilation and setup, will install the demo if needed):
https://retropie.org.uk/forum/topic/358 ... y-pi-model

If you have a Pi Zero, please test this, I'm interested to see how it behaves in one. I know a Zero 2 W runs it without trouble.

This has been updated to add some new performance options, which will be useful even when using normal GL1.
Add these in your autoexec.cfg:

Code: Select all

set g_machinegun_norecoil 1
set aimfix 1
set g_quick_weap 1
set g_swap_speed 2
set ogg_ignoretrack0 1
set s_openal 0
set gl1_discardfb 1
set gl1_lightmapcopies 1

If you're using Arch, Bookworm or Bullseye, also add:

Code: Select all

set gl1_pointparameters 0

This will give you "roundish" particles, instead of the square ones.

I'm assuming the base game works for you. Otherwise, you'll have to give more info on what you did.
For the expansions/mods, you'll have to clone and compile them separately. These are the ones I've tested:
The Reckoning: https://github.com/yquake2/xatrix
Ground Zero: https://github.com/yquake2/rogue
CTF: https://github.com/yquake2/ctf
Zaero: https://github.com/yquake2/zaero
make on each will generate a different release/game.so; you'll have to copy every game.so to different subdirectories where you have the game installed.
E.g. if you have the game installed in ~/Quake2, and you want to compile xatrix:

Code: Select all

git clone https://github.com/yquake2/xatrix
cd xatrix
make
mkdir ~/Quake2/xatrix
cp release/game.so ~/Quake2/xatrix

Don't forget to copy pak0.pak of this expansion to the ~/Quake2/xatrix/ directory. After this, you'll finally can play The Reckoning:

Code: Select all

~/Quake2/quake2 +set game xatrix
