Okay so your graphics card is Nvidia Geforce GT 750m? I also use this card. Is your laptop SLI, do you have another GT 750m? I'm no expert with computers but I'm wondering if your card might be forcing SLI and its causing graphical glitches. Don't worry if it is, it's simple to fix this.
I don't know what you mean by SLI, but the only other graphics card on this laptop is the Intel Integrated one, and yes, I'm sure the game's not using that.
Is your computer running windows 8.1? If it is I have some more ideas on what might be causing this.
Windows 8.0. Can't update because an earlier update to Windows 8 corrupted my profile and when I fixed the profile, the files for
all the Windows apps were completely missing (including the Store, which there's apparently no way to repair).
Also have you used Geforce experience to update your graphics card drivers? The latest version for the GT 750m is 344.75 which does not match up with the number you gave us. It could be you had a bad installation of your old driver. When the new one installs don't run anything else while it goes.
Last time I tried to update, my computer bluescreened and I had to reinstall the old driver in safe mode. If the driver's bad, then it's never shown itself as such before now.
Also don't use Red Werewolf I remember reading earlier that it was causing some major issues for other people as well. Try leaving just that disabled. I have had some graphical glitches due to the menu overhaul at times but nothing major or persistent.
Thing is, each of those mods causes the glitch independently, not just in combination with each other.
One more thing, try checking full screen but unchecking V-Sync and new timer. Also do you know what the refresh rate of your monitor is? Usually its 60hz 120hz or 144hz.
No luck, and I haven't a clue.
With Red Werewolf, did you click on Configure and select the option that corresponds with what you selected in Gameplay - Difficulty and Story? The drop-down menus are identical so that the flevel/scene work with Red Werewolf correctly. Having different options selected will not work; however, I did not put together those patches nor test them all in a full playthrough. 32 different difficulty and story mods are too much for one person to test. It could be that Wolfman and cmh175 didn't patch them correctly.
Yes, they were both set to the same thing, which is to say, absolutely nothing. They were both on "no change".
Side note: Any idea which of the mods, if any, would cause the game to crash upon trying to start the motorcycle chase minigame? Like, as soon as I hit start to begin the scene, the game throws an error and asks if I want to make an emergency save (an emergency save that loads me immediately into the following fight with everyone on 1 HP, which means an instant game over). I ended up just using the unmodded game to go through that segment, because I didn't feel like troubleshooting 2 dozen mods, or however many are in the catalogue provided in the OP. I know it's not Battle Models - Enemies, because I tried playing with that mod off, and it crashed anyways.
