If anyone is experiencing this issue when opening the game, try opening the options.ini in the game's local files and changing VertexBufferMethod=0 to VertexBufferMethod=1
Right click the game in steam, click properties, look at the local files tab, click browse local files. That is where you will find the options.ini
