This persists even if I stop the recording and start it again When not recording I have the game set to limit to 60fps, which it sits on quite comfortably. Unfortunately since then, my framerate will start around 40fps when recording and drop over 5-10 minutes to 30-40, then 20-25, then around 10-15 and stay there. These had large installation files and fragmented the machine a bit - I ran a defrag and everything seems OK. Yesterday, I installed Microsoft Office 2010 and VMWare vSphere for work purposes (sometimes I work from home). Finally I got to the point where I could comfortably record at 30fps.

I've been tweaking settings in my graphics control panel and within the game to get the FPS up. 256MB RAM graphics card (nVidia of some sort, few years old).I've recently started recording a certain Java based video game on my PC - along with audio commentary - using 32 bit Bandicam and Audacity for microphone input. I was umming and arring if this is the right place to post this, however the FAQs say this site applies to software and recording, amongst other things.

Bandicam video framerate goes higher
