Hey, I agree with you, why not try playing the game with the another graphic card. You can try to change the settings of the game and configure it according to the requirements. The advantage of the PC games is that they can be played with different graphic design settings. Many of the online stores like the Instant-gaming will provide you with more information along with the trial version of the game and the configuration settings.

Yes, I agree with you the game should give the choice to have 100 players per server.
