I'm making a poster of my physics research project for a conference. I don't have time to learn LaTeX at the moment, and I need to be able to type inline equations within text boxes - the only software I can think of that allows me to do this is PowerPoint 2010.
The problem is that I'm making an A0 sized poster and it's incredibly slow. When I'm typing text, it takes about 3-4 seconds to update. Scrolling and moving shapes around is even worse. I don't even have that many images, mainly just coloured squares and text.
Is it somehow possible to speed up PowerPoint? I've tried disabling hardware acceleration but that hasn't made any difference.
