A while back, someone made a add-on mod that puts "GPU"s in to the game, and your asking, what this does? It adds a way to run OpenGL Actions in-game, unfortunately, this mod has died a long time ago, It's also outdated (1.7.10). Could you add these "GPU"s?

So what's the issue?

While CCLights2 and CCGPU were very cool mods, I don't think they really fit within CC:T itself. Monitors are a headache enough!
