Oblivion Performance Runtime

An OBSE plugin that improves the Oblivion.exe runtime behavior between, you won't guess, Oblivion.exe and Windows the operating system your using right now. The Oblivion.exe was created around 2004 with 2004 operating systems, Windows XP and Windows 2000, you were not using Windows 10 and thus over the years Oblivion.exe and Windows drifted into compatibility zones leaving untested and broken behavior. This plugin asks windows in a modern healthy way and says "Can I have better threading? Can you prioritize me? I need more precision!" Oblivion on Windows XP did this already in a correct way, PR restores the asking/rumors maybe talking behavior between Oblivion.exe and Windows natively.

Overview

• []Oblivion Performance Runtime is a lightweight OBSE plugin designed to help smooth out Oblivion on modern Windows systems. [/]

  []The plugin does not alter gameplay records, scripts, leveled lists, INI settings, saves, or Oblivion's executable code. [/]

  []It loads with OBSE, applies a set of process-level runtime tweaks, writes a small log, and then gets out of the way.[/]

  What This Mod Does

  Oblivion is old enough that modern Windows can sometimes treat it like a background-era 32-bit application instead of a game that needs steady frame pacing.

  This plugin applies Windows-side runtime tuning while the game is running.

  Features:

  • []Raises Oblivion.exe to above-normal process priority.[/]

    []Requests a high precision system timer for smoother frame pacing and lower input latency.[/]

    []Keeps the game on a stable CPU affinity mask.[/]

    []Sets a preferred processor for the main game thread.[/]

    []Optionally hard-pins the main thread for anti-core-hop testing.[/]

    []Raises the main OBSE loading thread to highest thread priority.[/]

    []Enables the Low Fragmentation Heap on process heaps.[/]

    []Periodically trims the working set during long sessions.[/]

    []Requests improved foreground I/O priority for loading.[/]

    []Disables Windows 10/11 power throttling when supported by the OS.[/]

    []Reports Large Address Aware, WOW64, and DEP state in the log.[/]

    Requirements

    • []Oblivion 1. 2. 0416[/]

      []OBSE or xOBSE[/]

      []Windows 7 or newer[/]

      []A 32-bit compatible Oblivion install[/]

      Important:

      For 4GB memory support, you still need a Large Address Aware patched Oblivion.exe. You can use Oblivion 4GB Patch here on nexus mods. This plugin manages runtime behavior, but it cannot make an already-running executable see more address space.
