NVAC - New Vegas Anti Crash

Fixes the Windows 10 Anniversary Update + up-to-date Nvidia / AMD video driver crashes / issues for the following: Fallout New Vegas Fallout New Vegas No Gore (German) Fallout 3 Fallout 3 No Gore (German) Oblivion GECK (New Vegas) GECK (Fallout 3) Construction Set (Oblivion)

I may have a solution for you: NVAC.

NVAC (short for New Vegas Anti Crash) is an NVSE plugin that implements structured exception handling and sanity checking to reduce frequency of game crashes.

That said, I make no promises. This isn't a cure-all: it only tries to fix crashes related to access violation exceptions at specific offsets / addresses.

Since it's an NVSE plugin, nvac.dll goes in your Data/NVSE/Plugins folder.

After running New Vegas, you can double check that NVAC loaded by reading the nvac.log file found in your New Vegas folder; if nvac.log doesn't exist, consult nvse.log. NVAC does not fully support the German "no gore" variant of New Vegas; I simply don't have access to it to develop for it.

Feel free to submit exceptions marked with a "u" or "v" in nvac.log in the comments. They will usually be the final entry in the log (since an unhandled exception will crash New Vegas). Please also submit "e" or "s" entries in the comments for addresses listed as "preliminary" (in the readme) as that means I haven't personally verified them; New Vegas shouldn't crash when these are logged, so it'd require checking the log file arbitrarily after a play session. The log file is cleared each time New Vegas is started.

As a bonus, NVAC implements helper function inlining (it takes internal New Vegas functions that can fit within a 5-byte space and replaces the function call with the 5-byte-or-less instruction) which is a minor performance improvement.

NVAC can be removed at any time. NVAC isn't a normal New Vegas mod (esp / esm file); it's an NVSE plugin that modifies the game's executable code at runtime, but doesn't make any permanent changes. Nothing it does gets written out to a save the way changes made by esp / esm mods do.

Deciphering the nvac.log file:

19195402 _ 00310000 03060000 nvac.dll "19195402" is a timestamp which can be read as dd:hh:mm:ss (day, hour, minute, second); in this example, (November) 19th, 7:54 pm and 2 seconds.        "_" is a single letter code that identifies the log entry type, which I'll elaborate on momentarily. "00310000" is a memory address; for most entries this is the address of an exception (crash). "03060000" is an informative v
