Have you tried running Battlefield: Vietnam in Compatibility Mode in Windows 11? You can set Windows 11 to run the game in the version of Windows that worked best for your title. Below you will find a hyperlink that can step you though the process:
I hope this helps.
There is NO compatibility mode for Windows 11 and trying all the other OS variants don't work.
I think I found the solution. Your computer needs a drive other than the C:\ (system drive) working with Windows 11. On the C:\ Drive I couldn't get BFV to start let alone play in any compatability mode. I believe I tried them all. I have a brand new desktop, Set CLX, and can easily play high demand games, BF1 for example. Same with my Lenovo Legion laptop. I also have an old outdated Lenovo laptop which plays BFV on Windows 10, this laptop not being relevant. I have multiple external hard drives formatted to NTFS. This is the only option to get Windows 11 to recognize the drive(s). Also if there is another internal drive aside from C:\, you can try it on that one. Keep in mind all the tricks and steps to get BFV installed and also patched. Patch to which version you prefer, I just did a fresh install on a external for the laptop. It worked perfectly. Also keep in mind all Mods you care to install, just do as instructed. This should get you up and running on a primary system. I have two computers and I wanted to network them, and run the server on one and play on the other. My desktop monitor is a Hisense TV. If you have any questions about installing on the external/other internal drives, reply to my post, I will be notified. I won't address compatibility issues, for those you'll be on your own. I have seen a few in this thread. Read the whole thread. Cheers and Bon Chance!
