WebDescription. trunc returns a value equal to the nearest integer to x whose absolute value is not larger than the absolute value of x. WebAlso, is the uniform value a nice round number (0,1,2,-1 etc.)? There's a possibility that the GPU tries to recompile the shader if the uniform has a conveniently optimizable value (for example, having 0 in calculations would disable some of them completely and having 1 would remove uniform reads and multiplications). \$\endgroup\$ – christmas jello shots fireball
