A Quest Problem

Hello, i'm trying to do The Hand Behind the Ice Claw quest. But i have a problem. i found Altar of trial, and meat. but when i go there, i cant find find to where i use my flint or meat. i looked up at guides, it says there is a place to roast meat. but i cant find that in here.

Also, this is irrevelant with my quest, but sometimes after video's, game screen is getting red, after that game crash.

 

There's a small fireplace you roast it. its just clicking it as i remember.
the tiger will come out and you kill it.



you mean after the cut-scenes it crashes sometimes? ... video card driver...too much pressure on CPU/GPU ...try changing resolution, there could be a lot of reasons for it i'm afraid.

 

I looked everywhere in altar, but i cant find that fireplace. i looked everywhere in altar. but there isnt any of them.

nope, after some scenes, windows become red. its like when i open journal window, background become red instead of usual color.
i have radeon 6850 video card. it have 1gb gddr5 ram - 256bit.
