You misunderstood,
There is no way to improve the graphics yet. The bad graphics are caused because fuse needs to make the picture smaller. There are plans of adding a graphics filter to fusa in the future. this would improve the image a lot. But until the developer has time to make it work, you'll have to stick with the current result. The bottom line is, have patience, and hope for a breakthrough 
like we all do.
people do there best to get it working, your support helps :P
financially as well by the way... you can always donate a gift which would stimulate the development.
Could you drop me a link my kind sir?
