I know the Devs, or team of Devs are working on this issue. However I wish to make a plea for haste. Content at this time should be a very minute priority. Performance optimization, netcode and workaround for lag issues should be the main priority.
The content of this game is wonderful for the time being. Given, repetition of single game mode is slightly tedious, though this by no means can be considered to be static, and new things will come. It would be ideal if performance was optimal universally (providing min requirments are met), so that ones gaming experience on minimal content is exploited to its full potential.
Higher levels of performance will ensure a higher personal rating from each player on each bit of new content, because the content can be viewed and used in full force, allowing a much higher respect and regard for said content, therefore it's intention to be enjoyed to its full potential is acheived.
