I just noticed that my game stutters/has a hitch every 5-10sec, I tried using OSR but the stutter is still there. Here are my OSR settings: Master = { _comment = You can turn on or off each distinct feature from here. bManageFPS = 1 bHookCriticalSections = 1 bHookHashtables = 1 bReplaceHeap = 1 bLogToConsole = 1 bFix64Hertz = 1 bFlushLog = 1 iSchedulingResolution = 1 iMainHookPoint = 1 } FPS_Management = { _comment = Basic FPS stuff, switches to slow-motion on low FPS; in the past this has occaisonally produced bugs like the NPCs-dropping-dead issue; the issues are believed to be fixed but if you suspect you are having related problems you can try disabling bAllowSlowMotion which is the main suspect for any problems relating to FPS management bAllowSlowMotion = 0 MaximumFPS = 72 MinimumFPS = 15 iSmoothFrames = 0 iSmoothMode = 0 iSleepExtra = 2 bFPSConsoleSPAM = 0 iSchedulingParanoia = 1 iHardMaxFrametime = 200 } CriticalSections = { _comment = CS stuff helps both Oblivion and Fallout significantly _comment = most of the benefit comes from the Renderer+0x180 suppression (see overrides below) _comment = modes: 1=vanilla, 2=fair, 3=stuttering, 5=suppressed, 6=prioritize-main-thread, 7=deprioritize-main-thread bEnableProfiling = 0 bEnableMessages = 1 bUseOverrides = 1 iDefaultMode = 3 iDefaultSpin = 1000 iStutterLevel = 4 } Heap = { _comment = Heap replacement can produce MAJOR improvements in performance on Oblivion, only moderate improvements on Fallout _comment = It crashes instantly on Fallout, is moderately buggy on Oblivion _comment = Algorithms: 1=FastMM4 (requires external dll), 2=Microsoft (slow on XP), 3=SimpleHeap1, 5=ThreadHeap2 iHeapAlgorithm = 5 bEnableProfiling = 0 iHeapSize = 600 bEnableMessages = 0 } Hashtables = { _comment = This stuff is still new. _comment = The dynamic resizing option may still be buggy. bAllowDynamicResizing = 0 bUseOverrides = 0 bEnableProfiling = 0 bEnableMessages = 1 iHashtableResizeScale1 = 2 iHashtableResizeScale2 = 4 iHashtableResizeDelay = 20 } OverrideList = { CriticalSection = { CallerAddress = 0x701748 comment = Renderer+0x180, recommendation=suppress (mode 5) Mode = 5 } CriticalSection = { ObjectAddress = 0xB32B80 comment = MemoryHeap CS, recommendation=stutter (mode 3) Mode = 3 Spin = 1500 } CriticalSection = { CallerAddress = 0x70172A comment = Renderer+0x80, recommendation=??? } CriticalSection = { ObjectAddress = 0xB3FA00 comment = Unknown4, recommendation=??? } }
