It is hoped the next patch will contain some improvements we are currently working on along with a few other fixes.
These are PC only. The visual improvements will probably require dedicated video cards (higher spec PC's) but can be turned off for users with lower spec machines:
Shaders: Normal mapping.
A subtle effect that gives a little more depth to textures.Depth of field.
Another subtle effect that softens objects in the distance.Simulated weather. A significant improvement on the current static sky box. Clouds will pass and cast shadows, Storms and evening sky's will be possible and even lightening may return.
A quick cheltenham simulation has been uploaded to youtube:
