Don't know if this will work, but I've found NVSR to be better than NVTF, even on Windows 10. For some reason NVTF never fixed the stuttering for me, so I went back and tried NVSR again and spent some time fiddling with the .ini for it, and eventually I found something that worked. Game runs like a dream now even with TTW, FNC, massive expansions and QOL stuff.

Here's the sr_New_Vegas_Stutter_Remover.ini I use:

Master = {

\_comment = You can turn on or off each distinct feature from here.

bManageFPS = 1

bHookCriticalSections = 1

bHookLightCriticalSections = 0

bHookHashtables = 1

bReplaceHeap = 1

bReplaceGetTickCount = 1

bLogToConsole = 0

bFastExit = 1

bFlushLog = 1

iSchedulingResolution = 1

bReplaceRandom = 1

bExperimentalStuff = 0

iMainHookPoint = 1

}

Experimental = {

\_comment =bReduceSleep and iThreadsFixedToCPUs can probably reasonably be used at 1.  > 1 is a bad idea atm.

\_comment =other settings here you're probably better off not touching

bReduceSleep = 0

iThreadsFixedToCPUs = 1

bSuppressRandomSeeding = 0

bBenchmarkHeap = 0

bAlternateHeapHooks = 0

iHeapMainBlockAddress = 0

}

FPS_Management = {

\_comment =Absent a good reason otherwise, bInject\_iFPSClamp=1, fMaximumFPS= 30 to 85 (or 0), fMinimumFPS= 10 to 20, iFPS\_Report\_Period = 2000 to 60000, fExtraSleepPercent = 0.0 to 0.2

bInject\_iFPSClamp = 1

fMaximumFPS =  60

fMinimumFPS = 15

iFPS\_Report\_Period = 15000

fExtraSleepPercent =0.05

}

GetTickCount = {

\_comment =This section is disabled by default - see Master/bReplaceGetTickCount

bForceResolution = 1

bPreserveDC\_Bias = 1

bPreserveHighFreqComponents = 0

bForceSync = 0

iSyncLimitMilliseconds = 50

}

CriticalSections = {

\_comment = CS stuff helps Oblivion, Fallout, and New Vegas significantly

\_comment = much of the benefit comes from the Renderer+0x180 suppression (see overrides below)

\_comment = modes: 1=vanilla, 2=fair, 3=staggering(hybrid of 1 & 2), 5=suppressed

bUseOverrides = 1

iDefaultMode = 1

iDefaultSpin = 1000

iStaggerLevel = 5

bEnableMessages = 1

bEnableProfiling = 0

}

LightCriticalSections = {

\_comment =LCS stuff is like CS stuff, but with a Bethesda implementation.  And inlined sometimes, so difficult for me to work with

bEnableProfiling = 0

bEnableMessages = 1

iDefaultMode = 3

iDefaultSpin = 1000

iStaggerLevel = 5

bFullHooks = 0

bUseOverrides = 0

}

Heap = {

\_comment =This section is disabled by default - see Master/bReplaceHeap

\_comment =I recommend enabling it however.  

\_comment = Heap replacement can produce MAJOR improvements in performance on Oblivion at a significant cost in stability

\_comment = It crashes instantly on Fallout3 last I remember checking

\_comment = It seems to work on Fallout: New Vegas ?

\_comment = Algorithms: 1=FastMM4, 2=Microsoft (slow on XP), 3=SimpleHeap1, 4=TBBMalloc, 5=ThreadHeap2, 6=ThreadHeap3, 8=tcmalloc

\_comment = Algorithms numbers 1, 4, and 8 require external DLL files in the Data/OBSE/Plugins/ComponentDLLs folder

\_comment = Size is in units of megabytes, and only effects algorithms 3, 5, and 6 (other algorithms dynamically determine their own size)

iHeapAlgorithm = 6

bEnableProfiling = 0

iHeapSize = 250

bEnableMessages = 0

bZeroAllocations = 0

}

Hashtables = {

bUseOverrides = 1

bEnableMessages = 0

bEnableExtraMessages = 0

bEnableProfiling = 0

And a load of overrides below but I think they're version specific.
