Which version dropped xp support? (unless my info is wrong)

Not really a legacy question, had a look at the change notes and couldn't find anything. I have an explorer extension that reports the minimum windows version to run a given exe, and it's telling me vista for 3.7.1. I don't want to clutter my desktop with unzipping and checking each prior version without knowing if this tool is reporting accurately. Not a concern of mine, have been expecting the change for a while (but thought minimum would jump straight to 7)

Officially, XP support is alive and well, but only in 32-bit versions of GZDoom.

64-bit XP is incredibly rare so the decision was made not to directly support it - but that can still run the 32-bit version of GZDoom anyhow. That decision came sometime after 3.0.0 but before 3.4.0.

To figure out which versions had 64-bit XP support it would be necessary to get a PE image analyzer that can read the kernel version minimum setting, or learn its offset and use a hex editor to find it.

(edit: according to this commit that happened before 3.3.0's release, so 3.2.x were the final versions to have 64-bit XP support)

Do note that you absolutely need to pass the +vm_jit 0 parameter if using the 64-bit version of Windows XP, or it will run at 2fps.

XP support was dropped in 64-bit versions LONG before the JIT was ever introduced - so that should be a non-issue. This seems like a bit of a red herring - what kind of a setup do you have that would even allow this?

Yes. Yes it is. XP's officially made legacy as soon as TLS 1.0 among major websites were shed a few months ago.

Official support for Windows XP (incl. security patches) was also ended in 2014.

My fault, sorry for not being more specific. If running the 32 bit version of GZDoom in a 64 bit Windows, you need to disable the vm_jit or else you will get 2fps. At least that is what happens here in Windows 7 64-bit.

That also shouldn't do anything, because vm_jit is disabled by default on 32-bit builds - the JIT compiler's code doesn't work for 32-bit builds in the first place AFAIK.
