Hello, First of all, sorry for bad english, I'm not a native speaker. I downloaded the Demo version of rFactor 2 and started playing it, using the Xone Controller. Tried the Silverstone Circuit with the Red Bull Car, race with formation lap. During the formation lap and the race (no matter if I skip or not), my Frames drop dramaticaly from time to time. Normaly there are about 20 fps I think, sometimes it drops to 5-10 (no counter, I guess it's like that). I tried with AI and without. When I race without AI, the game starts dropping the fps dramaticaly, when I'm in 6th gear. Before that it's also bad. So I changed the settings, put all into low or disabled, same thing, not better. Tried to switch sync on and off. When I put the quality up, I get blackscreen in garagemode. I can hear when the mouse goes over the buttons. My PC: Acer Aspire V5-552G (Notebook) AMD Quad-Core A10-5757M 3.5 GHz AMD Radeon HD 8750M 2GB VRAM 8 GB DDR3 Memory Win8 64-bit So here are the settings I currently set. The computer shouldn't be too bad, it runs Skyrim on high quality with 60fps. I like the game so far. I play F1 2014 very much, but rFactor has tons of things which are better then in Codemaster's F1. I noticed this although I couldn't play it right So is there a way to fix my problem? Would be nice if sb could help me. If you know german, please use it, so I can understand it better.
