I bought Leadwerks on Steam 2 months ago which I haven't used much due to lack of time, and as I saw the early access of UltraEngine and saw the performances announced, well I decided to take the UltraEngine pro license. I tell myself that the first purchase (Leadwerks) will be used to buy Josh a good beer :-D.
In any case I can't wait to go home and try UltraEngine for VR.
PS: Sorry for my English I use google translate.
