TunaUppercut I've dumped another version of the game with the old box2d physics engine enable for you to try. Aside of that I can only try dumping the player higher off the ground so it doesn't skip the physics check.
Jayjay The overclock wont make a difference. Both my i5 and i7 are set the same way and I have a far steeper overclock on my gaming rig than TunaUppercut does too. From 2.4ghz to 3.66 or something worse. I think I can do a work around for this scenario just by spawning the player 16px higher at checkpoints.
Here is the file:
If this doesn't work I'll do the -16px y drop on the spawning. Aside of that maybe pausing before the level starts to let the event sheets catch up?
Also just confirmed is the age of the cpu, not the speed that is causing the slow down. Someone with these specs runs the game perfectly:
Intel Pentium P6200 2.13Ghz
4GB DDR3 Ram
Intel HD Graphics
This laptop is only 3 years old.
