User.cfg - allowed or not?

Hello everyone.

I'm an admin of Battlefield 3 portal for leagues, and toghter with staff we decided to not allow user.cfg in our leagues. Some users didn't like the idea, mainly because with user.cfg u can only change graphics things you can also change via in game options or in game consolle.

I'd like to have a detailed answer, in order to answer all possible question from league players.

This is an example of most common user.cfg

RenderDevice.TrippleBufferingEnable 0
RenderDevice.Dx11Enable 0

RenderDevice.ForceRenderAheadLimit 1
Render.DrawFps 1
PostProcess.DynamicAOEnable 0

WorldRender.FxaaEnable
WorldRender.MotionBlurEnable
WorldRender.MotionBlurMax
WorldRender.MotionBlurScale
WorldRender.MotionBlurNoiseScale
WorldRender.MotionBlurQuality
WorldRender.MotionBlurMaxSampleCount
WorldRender.MotionFrameAveraeCount

WorldRender.DxDeferredCsPathEnable 0
WorldRender.SpotLightShadowmapResolution 256

Some of these lines simply adjust a video settings you can also change in game options.

I'm asking if any of these lines allow user to change settings that in game or via consolle he cannot change. If not: why we should ban user.cfg from our leagues since players can have same results via in-game consolle?
