Anyone how to optimize this game for Multi Core?

[[Travis]]

A few months ago I upgraded from my old laptop to a gaming PC. The game however actually runs worse on my new PC due to it being multicore unlike my laptop. Anyone know any fixes or mods that can stop my fps from dropping from around 200fps to 40fps. It's really quite annoying. Not sure if it's anything to do with the fact that I'm running Windows 10.

Multi-core CPU tweaks[edit]

If you have a Dual/Quad core Processor or a processor with Hyper-Threading, then set these values to this:

bUseThreadedBlood=1 (default 0)
bUseThreadedMorpher=1 (default 0)
bUseThreadedTempEffects=1 (default 0)
bUseThreadedParticleSystem=1 (default 0)
bUseBackgroundPathing=1 (default 0)
bUseBackgroundFileLoader=1 (default 0)
iNumHavokThreads=3 (default 1)
iThreads=10 (default 3)


Otherwise leave them at the default.

However, it should be noted that an article on FiringSquad found no benefit in using these settings. Whatever the configuration of these INI variables, it is generally acknowledged that Oblivion makes very little use of additional CPU's/CPU cores. This may be because all of the functions that these variables enable multithreading for are not CPU intensive tasks, there appears to be no variable related to enabling multithreading for the main scene renderer, which would most benefit from such an optimization. Things such as the Particle System and Shader Effects are not used in excess in Oblivion, so using multiple threads for processing related to them will likely not have much benefit.

Despite dubious significance to performance, these options can effectively prevent or at least reduce crashes on multi-core systems.


Warning! Before you make any change, make a copy of your Oblivion.ini and your latest game save files. Changes in the Oblivion.ini can corrupt game saves or prevent the game from starting. In the event of an issue arising, simply replace the modified INI file with your backup and try using a backed up or earlier save file.

Acouple other sites say the same thing. you may try to limit your fps. you can search online to do this.

Yeah, not really. Even with the ini tweaks ^^^ the engine just won't utilize multiple cores. For more stability you can also add an extra line:
iNumHWThreads=2
to the ini in the General section. Same tweak applies to Fallout 3.

You can also limit your fps with Oblivion Stutter Remover. Capping to 60 fps or even lower might help smooth things out. The game wasn't made to run with 200 fps and I can imagine it would screw with some of the animations, and greatly hasten the onset of the A-bomb. Of course A-bomb is easy to deal with on PC, but it still sucks when it pops up.

Also limit the number of mods that add NPC's since AI chokes the game engine more than anything and is usually the single biggest source of fps-drop.

I forgot I use Oblivion Stutter remover which by default limits the fps to 30. I changed this to 60 by finding the ini file in the data/obse/plugins folder. Mine will not reach your levels but will drop at times. not so much with OSR.
Thanks Iwaloa.

Sounds like we need an OpenOB team haha

OpenOB would be awesome.

I wonder if there are enough skilled people who are as passionate about the game as with Morrowind though. Of course a fork from OpenMW that added a physics engine and formid processing would apply to Fallout3 and NV as well.
