Thunder&Lightning is running too slow

If Thunder&Lightning is running, but only with a very low frame rate, it usually means you either don't have the correct driver for hardware-accelerated 3D graphics installed, or your graphics card is old or rather low-end. In the latter case, there are a number of things you can do.

1. Disable Shaders

In your config.io file, find the following line:

Game_use_shaders := "true"

Change that to:

Game_use_shaders := "false"

This usually keeps TnL from running extremely slow or even crashing on older computers with low-end graphic cards. Additionally, you might try to reduce resolution.

2. Reduce Screen Resolution

TnL is preconfigured to run fullscreen in your current screen resolution. For desktop applications, this is fine, but for a 3D game, a resolution of 1600x1200 might be a little bit hefty. In config.io, find the following line:

Game_auto_resolution := "true"

Change that to:

Game_auto_resolution := "false"

Additionally, configure the desired resolution in the following lines:

Game_xres       := "800"
Game_yres       := "600"

Viable options include 800x600 (like preconfigured), 1024x768, 1280x1024, 1400x1050 or whatever your monitor may handle. A higher resolution means more work for the graphics card and hence a lower frame rate.

3. Wait for a new release or buy a new computer

Yes, the author likes stating the obvious. But seriously, TnL is under steady development and performance enhancements are always possible.
