Hello, Rfactor2 only works when I use the V1108-DX11-Open beta. (I use an Intel I7,32GB ram and use an Nvidia 1080 graphics card,disabled all plugins and set all special graphic options to none) I just purchased the nurnburgring and Porsche911 GT3 cup. When I start Rfactor2 in single player he hangs on verifying. I solved that by opt out of beta programs. As soon as I did that my newly purchased nurnburgring and Porsche 911 GT3 cup started to download. However when I start the non beta version ;whatever car or circuit I choose. it starts loading the track until the end and after that it returns to the launcher without error. So installed the V1108-DX11-Open beta again and then I can use Rfactor2 but if I select the Nurnburgring I get a error and the Porsche 911 GT3 is not present. Anybody else has this problem that only the DX11 open beta version works ? I'm quite frustrated that I cannot use my purchased items and probably will have problems if I buy new items in the future. this is my sysinfo.txt I found in a rfactor2 subdirectory : DX: DirectX 9.0c (4.09.00.0904) CPU: Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz @ 4,20 GHz QPC: 10000000 tps SRAM: 16348 MB OS: Windows 8 Build 9200 GPU: Monitor #1 VRAM: 4294966273 MB DRIVER: 0.0.0000.0000 GUID: 00001B80-0000-0000-0000-000000000000 GPU: Monitor #2 VRAM: 4294966273 MB DRIVER: 50.89.0065.0076 GPU: Monitor #1 VRAM: 4294966273 MB DRIVER: 0.0.0000.0000 Thanks for having a look at this.
