This made only a slight improvement, taking my average frame rate in the Cordon rookie village up from 14 to 17. I checked the FAQ, I've been round the block with STALKER games and mods before so I was already using the DX9 enhanced dynamic lighting renderer, and my grass distance and sun rays were already low, but I set them to off anyway. The game installed perfectly and launched correctly first time, load times quite normal, I've had no issues with it whatsoever other than I cannot get it to perform smoothly or look particularly good - in fact it looks sodding awful.

Nothing like those nice screenshots on the ModDB page. My frame rate for Call of Chernobyl is terrible, it's effectively unplayable, and it looks dreadful.
