It's also noted that the game is quite multi-threaded. By default, it seems to operate with no more than two threads, especially on AMD processors. I had to modify the game's configuration files to enable more threads, which increases the workload but isn't the intended default. Once I finish my work, I plan to capture a screen snapshot of the Task Manager and MSI monitor using the ini settings tweaks. The image I took was taken while I was exploring between the sanctuary and Tenpines Bluff. I usually don't see drops below 70%.
You can observe the number of threads in the ini files. For an AMD CPU, it should be 8. Other discussions have focused on optimization. The greater the number of cores, the better your Fallout 4 performance since the game struggles to utilize resources efficiently. It's not simply a power issue, but rather how effectively threads are used. Think of it this way: imagine the chocolate bars represent game frames.
Review your fallout4.ini configuration and insert the necessary entries. Adjust iNumHWthreads according to your CPU specifications (e.g., i5 = 4). Set general values as follows: [General]bMouseAcceleration=0uInterior Cell Buffer=12uExterior Cell Buffer=144bUseThreadedBlood=1bUseThreadedMorpher=1bUseThreadedTempEffects=1bUseThreadedParticleSystem=1bUseThreadedAI=1bUseMultiThreadedFaceGen=1bUseMultiThreadedTrees=1iNumHWThreads=8iPreloadSizeLimit=262144000 bMouseAcceleration=0 Turns off mouse accelleration uInterior Cell Buffer=12 uExterior Cell Buffer=144 Configures cell buffers for indoor and outdoor areas (cells define game map sections). bUseThreadedBlood=1 bUseThreadedMorpher=1 bUseThreadedTempEffects=1 bUseThreadedParticleSystem=1 bUseThreadedAI=1 bUseMultiThreadedFaceGen=1 bUseMultiThreadedTrees=1 Enables multi-threading across all game systems (results may vary). iPreloadSizeLimit=262144000 Helps prevent framerate drops when entering new zones; initial load may feel slower. It also defines the memory allocated for pre-loading assets (could affect performance on low VRAM or RAM). For additional options, check the in-game console for more settings—press tilde to open it in "~" tMta ONtMtrdfl ONtMtr. I don’t recall the exact meanings, but the game displays them when you enter them. tMt = Toggle multi-threaded
The game suffers from drawcalls bottleneck issues. I've checked AMD drivers above 5k drawcalls and performance falls below 60fps. Even when nothing is displayed, drawcalls remain high in Fallout 4. Fallout 4 | 12k drawcalls | 23 FPS Fallout 4 | 9.1k drawcalls | 29 FPS Fallout 4 | 1.7k drawcalls | 60 FPS (capped) Fallout 4 | 4.2k drawcalls | 57 FPS (actually 60 cap) pCars | 8.3k drawcalls | 46 FPS Just Cause 3 | 9.5k draw calls | 39 FPS Sometimes low drawcalls are just part of the problem.
What a fascinating take on the elderscrolls! How did it unfold for you?
Before improving my setup, the latest title available was Halo 1.
