Hello everyone, thank you to jackfuste for his vignette removal patch
Just wanted to report that as of the Survivors DLC Update February 15 2019, the vignette removal patch no longer works and causes the game to crash to desktop upon startup.
Is it possible for you to update it to work with the new dlc? and thank you guys for your awesome work!

or using Hex-editor replace the following bytes in re2.exe:
8B 87 3C 01 00 00 89 83 DC 00 00 00 => 31 C0 90 90 90 90 89 83 DC 00 00 00

Helifax, I am the guy who tagged your fix as causing glitches in the main menu and in-game on the PC Gaming Wiki. I hadn't gotten around to recording them until now so here it is:

There are 3 unique glitches present just in these 25 second clips. First one is the main title card having a blink out as the fade in effect draws. Most likely because the fade in effect uses the same shader as vignette. Second glitch comes from the character select screen, as you pick a different one there is a momentary flicker of the real-time rendered background popping in and then disappearing. Last glitch is when choosing difficulty. There is supposed to be a full black background to help highlight the selections. This is completely gone with the mod installed, again because it probably draws upon vignette shader to achieve.

It's a shame because all these problems are really CAPCOM's fault for coding it so poorly, but I doubt there's anything we can do about it. I haven't tested it far in-game but I believe anytime there's a cutscene you get a similar flicker artifact too as the vignette shader briefly changes. If you think there's anything that can be done about this, I'm sure all RE fans will greatly appreciate it.

Because it's not just the menus, it's ingame too with cutscenes like you said with the black bars pop in. And with a game that has you constantly going to the main menu during speedrunning where you mess up a run and reset, it can get annoying. Personally I find it far more disruptive than simply disabling vignette completely with hex editing and having those minor visual oddities from volumetric lighting and the skybox. If you run with volumetric lighting completely off for max performance like I do, then it becomes a non-issue entirely. Besides, I'm just trying to be as complete and transparent about what users should expect when using these things as they might see it and think their computer is artifacting when it's not.
