I was testing the 1.8 client earlier and was regularly crashing to desktop, usually when first joining a server but sometimes during gameplay also.
Heres a clip of one of the CTDs: https://streamable.com/cc6kay
Willing to attach a debugger to cod4 process and send results if someone can walk me through how its done, I already have VS if it can be done using that.
Edit: I attached the process via VS2017 but when I join a server I get the following exception:
Exception thrown at 0x0040C608 in iw3mp.exe: 0xC0000005: Access violation writing location 0x00000014. occurred
