Question about timedemos

Post by invictius »

I want to compare performance on a wad in zdoom and gz, but it was recorded on zd so of course it won't play back on gz. My question is, if I play through the level at the same skill setting on gz, is the timedemo framerate going to be similar? It's just a vanilla wad so it's not like looking in a direction that I didn't on the first demo would tank fps much.

Why do you keep posting threads like this?

Oh. I think I understand now. Carry on!

I'm doing a new round of benchmarks with gzdoom this time. The wiki said this:
if a demo was recorded with too old a version of ZDoom, the program will tell you it cannot play it back.
I tried the first version of gzdoom but they just went out of sync.

Most likely because you need to match GZDoom and ZDoom versions precisely. GZDoom was built upon SVN builds of ZDoom that Graf deemed 'stable' enough to release as stable where as Randy took a couple of years to release a new ZDoom version. So, either have fun with that or:

Turn off GZDoom's OpenGL and use its built in software renderer. It's identical to what ZDoom uses, so there won't be any differences.

That's not entirely true. Earlier versions of GZDoom had deterministic-breaking features that broke compatibility with ZDoom, and it was only later on before at least the game sim components were ported to ZDoom enough that ZDoom could play GZDoom mods.

In general, don't expect demos recorded in one source port to work in another, no matter how closely they might match.

Surely the same GZDoom version's OpenGL and Software sim is the same to use one port to handle both situations?

If played strictly on GZDoom, yes.

GZDoom was designed from the very start to be multiplayer compatible with both renderers.
