-Skin texture is large 1024x1024, and you computer is slow to load it
Half Life engine models won't accept a texture bigger than 512x512 or a similar size.

When you are changing skins change only V_MODEL because w_model and p_model can bust your game,destroy fps and on some servers their consistency is forced.
That depends on the w_ or p_ models you are using, not every model triggers consistency errors.
Still using the console command "mp_consistency 0" wouldn't hurt.
