Hey there, thanks for the feedback! Appreciate the time you put into testing this :)
So yes the game is built using the legacy GM Studio 1.4 engine and it's not terribly well optimised in terms of the graphics. It's surprisingly GPU intensive for a top-down game. The entire 3D pipeline that the game is designed around (d3d functions) don't exist in GM Studio 2 so there's no clear way of improving upon this unless I build a whole new game with a new engine. :(
Some of these performance issues have already been addressed and possibly will see improvement upon the next update (coming quite soon.)
Laptops with integrated graphics will get mixed results with this game. I Googled the model of your integrated GPU and apparently it only has up to 64MB of video memory (non-dedicated, so it's depending on your system) - there's the bottleneck in this case. I doubt your CPU is the issue. I would say that 512MB of dedicated video memory, or equivalent, is the minimum for Total Anarchy, and 1GB of dedicated video memory would be recommended. As a baseline machine, I test with a MacBook Pro i7 from 2011 that has Intel HD 3000 (up to 256MB VRAM) and I get 25-30fps.
