Horrible FPS problems with new vegas

[XZCJZX]

Hello Everyone

I'm kind of new here so I'd like to say thanks for letting me be a part of this amazing community. I have been dealing with a problem with new Vegas for the past two weeks. my system is a GTX 980 and Intel 4770 K 16 gigabytes of Corsair Dominator RAMand my new Vegas install is on an SSD all connected to a MSI GD 65 gaming motherboard. when I started playing the game with no mods installed I was getting about 40 to 50 fps around good town outside doc Mitchell's house. after installing an enb and around 130 mods I now get from anywhere between 10 fps to 39 fps and it steadily decreases the longer I play. I also experience screen tearing, and in some places absolutely unplayable fps (2-7 fps). I have new Vegas script extender, new Vegas stutter remover, Fallout New Vegas 4 gigabyte patch, and then call out fake full screen mod.I don't understand what the problem is my computer should be destroying this game. MSI 's Intel over clocking utility says I never use more than one core and never use more than 28% CPU, and afterburner says I never use over 40% of my GPU and the vram is barely being used at all. I've also done all the ini tweeks I've ever come across googling this problem nothing seems to help. vsync off the number of hardware threads set from anywhere between 2 to 8 everything threaded nothing helps. I've tried clean installs updating drivers everything I could think of. Please help!!!!

You're held back by the CPU, judging by 40% GPU usage and horrible framerate. You can set the game to use a bazillion threads but it will only use two somewhat properly and out of those two, only one will be used 100%.

 

In your particular case it sounds like the game is using two threads on the same core so disabling HyperThreading might help.

If it's not HyperThreading at fault (technically this shouldn't be a problem, as the motherboard's BIOS is supposed to enumerate logical cores last in the MADT, but that's making an assumption that everyone had their morning coffee and followed the directions, but I've seen systems that don't do this right so turning HTT off is worth checking), it may be some other application you have running that affects the 3D drawing (e.g. FRAPS, amBX, some recording applications, etc) which can really impact NV's performance. Also, you didn't mention, but are you trying to force very high levels of AA or some other image quality thing thru the nVidia driver? That may also be causing trouble.

The OP should post on the New Vegas board remembering to include his load order, it's probably a mod or combination of mods causing the issue.
