Subject: optimize R_AnimCache_UpdateEntityMeshBuffers to use memcpy instead of VectorCopy... 
X-Git-Tag: xonotic-v0.1.0preview~230^2~43
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=8e6b20a776721497beebfbb19ce34d6111082098;p=xonotic%2Fdarkplaces.git

optimize R_AnimCache_UpdateEntityMeshBuffers to use memcpy instead of VectorCopy, Steel Storm 150fps -> 167fps (now only effective in D3D mode, as this path is usually not used any more in OpenGL)
