High memory usage and low FPS

[mbernarr]

Used nui+ for a long time and I've always had some issue with low FPS and high memory usage but its at the point of where I cant pvp at all even w/ my graphics on fair settings b/c I am pulling maybe 5-7 FPS when I shut all my addons down i pull 15-20 fps. NUI+ is pulling 36.MB of memory. I run NVIDIA GeForce GTX 460 SE
processor AMD A6-3600 with 4096 MB ddr3 i think. I don't know if it's just that my card is old but that's what I have to work with every site tells me that I should have no issues running MOP or 5.0.4. Is there something I am not seeing. All my other addons that I do run hardly take up any memory.
