If I may jumps in here..
I already have a bug thread open, I dont know if you have access I am sure you do. but here we go.
Here's a list of what I had found, some have been fixed and some on the list to do.
Presets and particles are hit and miss, some of them crash you out and others just show a diamond on the scene
Tool's > Mesh merging and Resource collector crash you out.
Lights If your going to use point lights then you must have a directorial light in your scene, if you don,t require a directional light then set it to zero (0).
Had some issues with lights not keeping there settings (spotlights), but seem OK with the default scene (strange one).
Dynamic Models (right click) the knightress crashes your system dont use the 3rd person, the FPS one works fine, some of the others also dont work.
SkyBox on occasion when loading several SkyBoxes one after the other has caused a crash.
Tech Demos A lot of the Tech Demo's dont work, with some of them its the presets or particles but like said above they have been listed (above), also errors in the Tech Demos leading to crashes I presume these are due to the LUA problems I seem to keep finding..
The Lua Hooks and commands are getting looked at and its a bloody long list if you want to chip in and help test them to see if they have been effected.
The only ones that I have found to want to cause problems are ones that reference other scripts such as fps system and damage system but its early days will keep banging away at the list and eventually pass on my findings lol...
Think theres a few more will have to see when I get back to testing tomorrow, had my daughter stay over the past couple of days..
