If you encounter crashes or other visual bugs, please try these steps first:
If you have a modern GPU try to update your drivers and don't do any of the following steps...
If you have an old GPU/Computer, try these:
Inside the client press F1 and type (or copy & paste)
gfx_opengl_major 2;gfx_opengl_minor 0
restart
if this didn't help try:
Inside the client press F1 and type (or copy & paste)
gfx_opengl_major 1
restart
If you still encounter bugs you can ofc still ask/report anything (edited)
