WARNING: 'Perfect' Mode required 32 bit color, 24 depth and 8 bits for stencil
WARNING: 'Perfect' Mode required latest drivers with 'vertex buffer' support
WARNING: 'Perfect' Mode required pixels shaders
WARNING: 'Perfect' Mode required latest drivers with vertex shaders support'GL_ARB_vertex_program'
WARNING: 'Perfect' Mode is not supported for this combination of hardware and drivers.
Your laptop PC has very low and limited graphics functions and performance.
Having "x" check is only Multitexturing.
That might make impossible to draw transparent objects or lighting effects correctly.
When you'll try to change graphics settings lower and lower, in some cases, you'll succeed to play IL-2 1946 with cheaper drawing.
