NWN and Radeon HD5450 (Neverwinter Nights)

Hello everyone. Has anyone encountered NWN refusal to work on this vidyuha? Even nwloader crashes. Launched nwconfig, changed its settings - don't care. When you start nwloader, a splash screen appears - and a crash. If through nwmain - a black screen with a proprietary cursor - and a crash. Last firewood, checked at the office. Piggy. It works fine with Radeon X800, but the old lady started to slow down. There is also a good nVidia, with it, too, no problems, but due to the sharp rise in prices, I still save it for more demanding games. DirectX is fine. It is interesting that Skyrim on the Radeon HD5450 is quite tolerant, NWN2 - too, but the old man NWN1 does not want.
