How to unlock pre-1.27 patches

If you want to do RTA runs but your computer isn't the fastest, then you might want to try recording with Nvidia Shadowplay (assuming it works with your particular computer). Shadowplay records using your GPU and thus doesn't cause any slowdown to your CPU, which can lead to better game perfomance while recording.
