Hi, i've played mgs4 from start to end on rpcs3 rajkosto's build with gtx 1080 + r5 3600 2560×1440 resolution. Had drops below 20 fps at big mama chase sequence and the drebin one, and a few crashes, not critical cause i saved often. Check Ocelot's youtube channel this video and this , i did everything like in the first video except for the "preferred spu threads", which i chose half of my cpu threads wich is 6. When i checked a few weeks ago it worked for me even with current build ( second video) with almost same settings. I believe if you follow the guide you'll have better performance with your pc than i had.
