Bandicam is a very old, and pretty bad program if u ask me. There are much better alternatives out there. Would you answer me Gamabuntu, out of pure curiousity, what you find awesome in Bandicam? Cos last time I watched your videos I think it was 720p and pretty bad quality overall.
Nvidia have Shadowplay (close to lossless quality with almost no impact on performance + small filesizes)
If you have a new(ish) AMD card, I would download OBS (Open Broadcaster Software), and record with amds VCE encoding setting (which is the equivilent of shadowplay (nvidia)).
Its rly easy to get started making videos, but if anyone wants a quick tour in Sony vegas I could upload a guide, pm me if it would be of interest.
