Good afternoon. I apologize in advance to the admins if this topic is not relevant, but I couldn't find an answer to my question anywhere on the internet. Here's the question: After installing all the patches up to 1.5.1, the game started lagging, regardless of whether the graphics settings are high, medium, or low. Is there a way to fix this? I have a 4tech wireless mouse, but it's not the 7x series. Before the patches, everything ran smoothly on maximum settings. Here are the computer specs: CPU: Core i7 3.4 GHz RAM: 16 GB Video card: GTX 560 2 GB Metro, The Witcher, and StarCraft didn't lag at 1920*1080 in 3D mode!
