So guys, what is performance like with this one?
STALKER runs silky smooth for me with any mod installed, but I had some problems with Clear Sky. Mostly a choppy framerate; sometimes really smooth and sometimes quite choppy. I realised you could lower a lot of the effects (sun rays, SSAO, etc) and have them look no worse yet get a nice performance increase.
Is Cal of Pripyat similar in iffy engine optimisation? I cant help but feel the crew are dumping all the newest fanciest graphical effects in their engines without spending any time to properly optimise and tweak them.
