The WAR team have written an update detailing improvements they're currently working on, such as:
More information.We've got some great plans for improved graphics options as we continue through launch. Our number one priority is player performance. It's important in an RvR game for performance to be smooth and allow the game to be accessible to as many people as possible. In order to achieve our goals, we had to ensure a certain level of compatibility between devices. With all of the combinations and options available, we wanted to keep things simple and accessible to everyone.
With that in mind, we have a fix that may improve the ability of higher end machines to load textures, and we will continue to smooth out the process of the way textures load on your screen. In addition to this, we are exploring other options to add which will further enhance the graphics for mid to high range computers. For now, many users are able to turn on features such as anti-aliasing and anisotropic filtering using their cards drivers.
