I think Fallout 4 is just a messed up game. I love it and play it daily but the game is messed up. I run 2x R9 270X Crossfire and I have everything set to ultra. I have a CONSTANT 58-60fps but every time I am in some place where I see "a lot of the world at once", like on top of a tall building overlooking a huge area or on top of some other sort of structure I immediately drop into lower teens. Usually 15fps and as low as 13fps.
Clearly this is not an issue with my computer hardware, since if this was the case I wouldn't get 60fps literally everywhere else.
If I play with the settings and set the view distance lower and shadows lower I can get up to 23fps or so but usually the increase in fps is a lot lower and the difference is really miniscule.
The devs need to realize that there is a real problem and fix it already! This is getting really annoying.
I don't care that someone with a GTX 980Ti and a Skylake CPU doesn't have these issues. Most games run ok on a wide range of hardware and do not require a $2000 rig to run well. I am not going to upgrade my PC in sig just because ONE game wont run as well as I want it to.
I play F4 on a s775 q9500, 16GB ddr2 ram and an r290x. Maxxed on on the graphics at 1080p and I get no slow downs at all. So, if my antiquated system can play it either one of those will play it great. I do have all SSD drives and they make a huge difference.
I can second that. The Conroe system in my sig runs FO4 just fine but the fps is really low because of the low end gfx card. I should bench it with another GPU sometime... Then again the LGA 775 CPU is working at 100% at all times while running the game so pretty much if its not a bottleneck, then at least definitely the very limit.
