[GhostSlayer0602]

Hey Guys,
im in need of some help and have tried a bunch of fixes that i cant seem to get it working, my sli for battlefront 2 gives me significantly worse fps then 1 card, but for some odd reason it does sometimes work and gives me 80-100+fps at 1440p ultrawide, but the display glitches out and has a werid blue artificats all over the screen, ive tried changing g-sync on and off, changing sli profiles but i just cant seem to get it working, is there anything im missing? THANK YOU!
my specs are:
i7 4790k
GTX 1080 FTW SLI
16GB DDR3 RAM
screenshot of sli performance is attached for reference

Artifacts and worse performance is usually a sign of a bad card. Test each card by itself and make sure you get the performance you should have. A bad slot on the board or not enough pover is also possible.
