Please submit the latest build of the rF2 executables to Nvidia so that an updated working SLI profile can be created. The current one has not been updated in years and does not work very well.
rFactor2 is not SLI optimised game at all. When new build or new Nvidia driver is released are users forced to spend hours to figure out which SLI Compatibility Bits is going to work this time and if there is SLI Compatibility Bits which is going to work , is it posible to play game I bought at all? At the moment there is working solution to SLI: http://isiforums.net/f/showthread.php/25620-Perfect-SLI-Scaling-w-rFactor-2-Great-Job-ISI! forcing to use old Nvidia drivers 353.30 or 353.55. How long time we must stick to old Nvidia drivers ISI? Come on ISI it is time now. You are going to release game on STEAM. I think STEM crash kids don't take this as nice as rFactor2 supporters have taken so many years. http://www.nvidia.in/object/sli-technology-games-in.html
Under W8.1 I find Spinelli's Sli profile works well but under W10 I'm having poor performance with the Nvidia drivers, no matter which I install. SO yeah, an updated sli profile would be great. My next GPU upgrade will be once the VR headsets are out and will want to probably go single GPU if things aren't sorted out here.
There is Official NVIDIA SLI Profile Request Thread and when pCars was beta Nvidia created temporary SLI profile when asked. Lets turn on the heat on Nvidia and se if we get lucky too. Please give you support here: https://forums.geforce.com/default/...-profile-request-thread/post/4697021/#4697021
