bronxxx Posted March 4, 2020 Share Posted March 4, 2020 SLI Compatibility bits not working anymore? Greetings, it seems that the SLI compatibility bits for ARK are not working aynmore. Using 2 x 1080TI, the 1st card got full 100% while the 2nd one only is about 9%. Does anyone got this working with both cards active ? Which settings are you using in inspector? Kind Regards Link to comment Share on other sites More sharing options...
BeansonToast Posted September 5, 2020 Share Posted September 5, 2020 Hi Bud - im in the same situation with x2 watercooled 1080's - card 1 at 100% most the time, card 2 barely getting out of bed so to say - did you ever find a solution or are we stuck with industrial fan heaters? Thanks Link to comment Share on other sites More sharing options...
SamueL125 Posted March 3, 2021 Share Posted March 3, 2021 Good day! I'm using driver 441.87. When using the existing (factory) SLI profile for the ARC game, both video cards are loaded only by 40-50%, there are AFR lags - in general, the performance is lower than with one video card. Changed the factory SLI profile as follows: Set the value of the parameter "Sli Compatibility Bits (DX10 + DX11): 0x080222F5" Now one of the cards is loaded by 60-80%, the other - 15-20%. The overall frame rate is slightly higher than with a single video card, however, it is still not high. At the same time, in this mode, there are no so-called AFR lags, which tells me (a person who has been using multi-GPU systems for several years) that video cards can cope with the load, and the performance problem lies elsewhere. In my case, it seems to me that the 7800X processor is too weak for this game with two video cards (by the way, the game itself uses processor resources very poorly).
