Hi, after installing Blood and Wine I have a decrease in FPS. Exactly, when i play more than 5 - 10 minutes my FPS falls to such values that is impossible to play. Lowering graphic settings does'nt help. I have changed settings in NVIDIA's panel and nothing. I used option "repair game" in GOG Galaxy. Can you help me ? Had anyone had such a problem ? And sorry for my bad english :)

It could be a heat issue which may cause your CPU or GPU to throttle. Try playing with the side of your computer open and with a fan blowing into it. If the frames stay stable clean your CPU and GPU fan from dust. A program like HWMonitor can also tell you how hot your components get. Iirc most CPUs/GPUs start to throttle at around 100°C and around 70°C under load is ok. But that highly depends on your hardware and which component you are looking at. Otherwise I have no idea, sorry.

Thank you for help. My temperatures are around 85-90 degrees and still when i play more than 5 - 10 minutes my FPS falls. I don't know what is this. I read several forums and a lot of people had problem with FPS's falls after installing Blood and Wine.
