I edited my fair share of videos and i think i can say that this program is great for reviewing demos but if you want to make edits and highlights its never gonna be good enough, csgo demos may be laggy and take a long time to navigate but it has the console, the csgo console with the addition of HLAE which gives you more console commands offers way more than this program can right now and propably some years in the future, im looking forward to how good it can be but right now its just faster than the csgo demos and thats it, i appreciate the effort they put into this but charging 5 euros for it right now is unreasonable.
None. They wont ship with CS:GO files... it uses files from your CS:GO installation. The thing is with this, it probably not as accurate as the game playing the demo itself.
