If you have a powerful GPU card, you can test it out.
Not really, by todays standards (you wont impress anyone with an GTX960M or an GTX780Ti SSOC+GTX770 today anymore, Laptop, which gets more use is from 2015 and My workstation, which only does Heavy 3D-Render Stuff usually is even older. i dont upgrade Hardware that often, Next upgrade is planed in about 5 Years, that will have to do untill then). thats another nice thing about Twixtor, it runs fine on CPU only and does that pretty fast actually considering what its doing and the Hardware its running on.
Thanks for the Link anyways. Will take a look at it.
