Windows 7: Fallout 3 on Windows 7 w/quad core

24 Nov 2010   #21

Windows 7 RTM

FNV has its own issues, but I found something that fixed my problems.

One was the directx performance issue, which has now been fixed via the latest patch.

The other was horrible, brain bleeding stutter/lag when turning with a lot of NPC's in the area, dead or alive.

This thread was most helpful, even though it referred to Fallout 3 and not specifically to FNV:
Fallout 3 still Stuttering - 195.62 - NVIDIA Forums

I did a few more tests, specifically in the player house in Megaton. I get the hang exactly once in that house; after that I can turn around all I want without any hitching.

These are the changes/tweaks I did, only listing the ones I believe to be somewhat relevant:
  • Set "iPresentInterval" to 0 in Fallout.ini (disables v-sync)
  • Set "iNumHWThreads" to 2 in Fallout.ini (fixes crashes with 64bit OS and quadcores)
  • Set AA transparency to multisample, disabled v-sync and set pre-rendered frames to 0 in NVIDIA control panel
  • Set AA to 4x, all options to "Ultra", Water Reflection Quality to "Medium" and disabled Transparency Multisampling in the Fallout Launcher

Gets me extremely smooth 60fps outdoors and 100-150fps indoors; no hitching except the one-time occurence inside the Megaton player house.

(I replied):
Thanks much for those settings. They seem to also fix issues with Fallout New Vegas and stutter while turning. That lag/stutter issue was worst when near NPC's, dead or alive. It was pretty much unplayable and vomit inducing.

Also, here are some other multi-threaded tweaks that seem to improve performance on my GTS 250 w/Quad core AMD (update them in FalloutPrefs.ini):

Windows 7 Professional x64

Decided to install fallout 3 on my new machine to give it a good run through. Was having the same crash every 5-10 minute issue, sound would keep going. Had to manually kill task. Edited the .ini as stated in the fix, and it worked. Game version I have is final release, game of the year edition. Before steam got their paws on it. Thanks to whomever put up that fix.

Still freezing

I did the trick with the fallout.ini I also downloaded the 1.7 patch. It still freezes on me. I feel like I have to save every 30 seconds and inch my way to outside the vault. I do not know what else to do, I loved the game on xbox. It seems, that I have had to do work to every game I purchase for the PC. PLEASE ANYONE HELP ME OUT!
