Patch for Heroes 5 v.1.2 [Discussion]

After installing patch 1.2, the game became a bit "laggy," especially when: (-) Resources are being collected, etc. (-) Entering/exiting a castle. (-) During battles, the skill casting speed is slightly slower than in versions 1.1 and 1.0. and so on... + Some textures and lighting in the Dungeon and Necropolis castles have been fixed. SOME ASPECTS OF THIS PATCH ARE WORSE THAN IN VERSION 1.1! P.S. System: Radeon X850 512mb; RAM 2gb... Is there anyone else experiencing a similar problem?
