fallout 3 isnt using GPU

[notechlogic]

So I bought fallout 3 on a steam sale knowing it was poorly optimized for windows 7/8 and have managed to at least get the game working on my PC. The problem is, my 780ti is barely being utilized, the power isn't going up by more than 3-5% and i'm getting a choppy 25fps average. EVGA precision X show's the power isn't increasing at all, and i'm thinking that this game is either trying to use my cpu for graphics input or for some reason just isn't utilizing my gpu. I can run every other game fine so i'm sure it's not a hardware problem

whats your full pc specs and do u have updated system and hardware drivers?

 

[rgd1101]

there a tweak on fallout 3 for multi-cores processor, google that.

I7 4770k, Evga SC 780ti, 8gb gskill ripjaw, gigabyte z87x hd3 mobo, some cheap Toshiba HDD. All drivers are up to date. U think multicore tweak would make a difference with GPU utilization?

whats ur exact full pc specs?

 

[notechlogic]

what do u mean exact? the only thing I left out is the PSU which is a thermaltake sp-850m the ram is a ripjaw X 1600mhz, 9-9-9-24 timing, cpu is stock speed but I hardly see how any of that is relevant

 

[iceclock]

its relevant to rule out hardware issues and incompatibilities.

have you defragged and scan disked ur hard-drive lately?

Did you install any mods that might interfere with each other?

Also, I think there are some mods for the game, so it utilizes more cpu cores (or something like that) and a tool to set the flag that it can use more than 4 gb RAM.

I already have the 4gb ram patch so I could start modding, sadly I haven't even got vanilla stable 🙁

 

[notechlogic]

I degragged and still nothing 🙁
