I use custom generated normal maps with a program that I've found less than satisfactory. While they're not impossible to use, it does result in some artifacting on HIGHEST unless you fiddle with the settings. I'm happy to say I have a better solution in place now and in the next few weeks I'll be updating the normal maps to ones that are FAR superior to the current iteration.
I'm going to wait for this sale to be done then I will do the necessary updates as it'll require taking them off the store temporarily to update.
