Loving Rfactor 2. Purchased steam edition during summer sale. Runs fine when forcing 32 bit option in settings, but will not launch when 32 bit box is unchecked. Confirmed that Rfactor 2 is runnng in 32 bit via task manager. Noticed when attempting to launch in 64 bit mode that Rfactor2 "running" on left of steam screen will flash what appears to be "synch" for an instant before it fails to launch and just reads Rfactor. I have googled all I can find on this problem and searched these forums as well with no solution that seems to work for me. I am running Windows 10 home edition 64 bit, I-5 760 processor, 12 gb DDR3 ram and GTX 1050 graphics adapter. Any and all help is appreciated. Some tracks like Road America will not load and I suspect that Rfacotr is not accessing enough ram.
