Thank you! 
[ol] [li]Start game [/li][li]Go to Quick Menu through Command > Menu Toggle (Windowed Mode) at top of program [/li][li]Scroll down to Shaders at the bottom [/li][li]Load Shader Preset [/li][li]Choose a folder, such as crt [/li][li]Pick a shader inside [/li][li]Go back, press Apply Shader Changes [/li][li]Menu Toggle back to the game [/li][/ol]
This will make your computer run hot. Use a temperature monitor like Speccy. If your temp reads over 80c, turn off the shader.
Thanks friend!!!
