- The loading time is too long and demand on video memory and memory capacity too high. If you want to play this game smoothly, you have to prepare a 512MB video memory display card (7900GS at least) or 2GB memory or long time waiting.

- AA effects are bad and it didn't support HDR+AA -  If you want to open AA you must turn the light and shadow effects to lowest and this will cause the other options closed automatically. HDR+AA is most of the game developers used now. It seems that Stalker still rest on several years ago FarCry HDR level. So you have to improved definition (ensure your equipments are good enough) or low the light and shadow effects to open 4x AA which equals to the other games 2x effect.

- Vision far scene effect failure, shader layer upon layer

- Physics effect miss

- Shoot feeling is bad  - It didn't extrude the true feeling or adapt to the game, it is really difficult to aim and shoot.

- The hardware demands are too high - though the equipments are really high, the fps won't improve a lot. The same scene fps different a lot cause the game equipments unbalanced. So we draw a conclusion that this game didnt optimize the new generation display cards well. Besides Geforce 8800GTX, we felt Radeon X1000 and Geforce 7 series didn't exerted their best performances.
