I'm running an MSI 970 Gaming Mobo, AMD 8350 CPU and GTX 1080 with 16 GB ram and 750 psu. Have tried a fresh install of windows 7, separate drives, windows 10, nvidia profile tweaks with profile manager, all in game settings, and have windows 10 slimmed down and optimized with various services turned off. Some will say amd's are worse than intel but have no other issues with any other game. The vanilla GTA V averages about 40-50 fps with fraps but soon as rage loads, drops about 10 fps then lspdfr loads with a few plugins drops to about 15 to 20 fps. Then when the ai start crashing into each other or do stupid things, or traffic backs up can see frame rates drop into the single digits. It really sucks and I'm not dropping $500 for an I7 (mobo, cpu and ram) just to play lspdfr. Rage needs an update and whatever is causing the huge drops in frames for lspdfr needs to be fixed. I try to avoid downtown even with population settings turned down. Have found no changes with in game settings make much difference. Try running with direct x 10 and hang around sandy shores or some of the outskirts. Thats what I'm trying to do and helps a little but the single digit frame rates are almost unavoidable at times. Have removed all plugins and noticed little improvement with low frame rates.
