The game plays as in the above video (lighting broken, glitches everywhere - this happens regardless of resolution scale)
UNLESS Strict rendering is enabled. once this is on, the lighting works perfectly. the framerates are at near constant 30 with very minor shader compilation stutters.
one thing i found is that the audio stutters like crazy once in game. however, if you turn the effects audio to 0, all other audio (music and dialog) plays perfectly. it's weird not hearing yourself shoot but the game is otherwise very playable now.
*Edit* - after trying to continue on from yesterday i've found saves are broken. The saves are there but the game will not load them. Animations continue in the background but the game goes no further than a black box stating that it is reading save data
