Dedicated without ShaderApi and DirectX pre-alpha
The instruction at 'CalcPropStaticFrustumCull' [0x14028F3B0 + 0x5C7] moves RSP + 0x70 into the R13 register. RSP + 0x70 seems to contain a pointer to collission data for that particular prop model. When running NoShaderApi() and passing the dedicated server the '-noshaderapi' command line parameter, RSP + 0x70 will be a nullptr. This has to be fixed to have prop static collissions on the server.
