FIX FOR CRASH AFTER MAIN SCREEN!!

[RonaldMcManSlaughter]

Guys I wont take credit for this, some russian fellow figured it out but here it is!

Close steam! Then on your desktop create a bat file with the following inside:
start /affinity FF C:\"Program Files (x86)"\Steam\steam.exe

Then launch the bat file which will launch steam. Then you can launch prototype 2. The game will play. No crashes or lag or hangups on ANY level even the claws mission. Remember to restart steam when youre done playing as I think this changes the app core affinity! Works for me every time!. Enjoy!!!

This actually works for me!

I have tried every single discussion and suggestion and none of them worked, but this actually works! Thank you so much.

Also, I updated the script like this. It kills steam if exists, then it spawns Steam with Affinity and auto plays Prototype 2. Ensure game id matches yours by making a desktop shortcut.

Then you can quickly open the game this way.

taskkill /f /im Steam.exe
start /affinity FF C:\"Program Files (x86)"\Steam\steam.exe steam://rungameid/115320

That's a pretty good work around since I don't think you can disable processors easily these days via Motherboard and a horrible idea. It's nice to know the Windows start command allows you to set this for a process!

FROM: https://www.computerhope.com/starthlp.htm

start /affinity

Specifies the processor affinity mask as a hexadecimal number. The process is restricted to running on these processors.

The affinity mask is interpreted differently when /AFFINITY and /NODE are combined. Specify the affinity mask as if the NUMA node's processor mask is right shifted to begin at bit zero. The process is restricted to running on those processors in common between the specified affinity mask and the NUMA node. If no processors are in common, the process is restricted to running on the specified NUMA node.

Worked for me, Thanks!

For those who install Steam outside of the Programs folder, which you should, of course modify the script to your directory.

For me, it's:

taskkill /f /im Steam.exe
start /affinity FF G:\Steam\steam.exe steam://rungameid/115320
