[RESOLVED] Framerate Issue
Castruccio:
I have been playing AVWW for a while now but with the new feature that shows the framerate in the message window I have been able to confirm a dramatic fluctuation in my framerates that I don't think should be occurring given the demands of the game. I am running a 2.4Ghz i5 450M with 6GB ram and a Radeon 5650m with 1 GB ram and the latest Catalyst drivers. I have the game set on 1280X768 resolution.
I am currently fighting a Giant Blue Amoeba and my framerate when it attacks drops to about 15 fps. In forest areas I get about 24fps, and in deserts I can push around 35. In buildings I usually fluctuate between 20-40fps, unless a lot of enemies are attacking in which case it drops to around 15.
Given the high demands of some of the 3D games I run, it strikes me as odd that I can barely push 30fps on AVWW with the resolution turned down. Any thoughts as to why it is so choppy sometimes? Is anyone else having these sorts of dramatic fluctuations?

If you hit F3, what does it say for the number of textures drawn and the number of texture swaps? I've not been hearing about this sort of dramatic fluctuation as a general rule, no.
In terms of the demands of a high-powered 3D game versus a 2D sprite-based game, don't get me started. We have way more texture RAM to use than they do, most of the time, and a lot more state changes on the GPU. That said, my FPS on an 8800 GTS almost never drops below 120.

Yea, don't get Chris started on 2D vs 3D, he's already had to explain to me more than enough times why drawing 100 rectangles on a screen is an expensive operation in 2012 :)

When the framerate falls to 20 fps in a forest area with several enemies on screen, the textures drawn is around 234 and the texture swaps is around 74.
It may also be worth noting that unlike other games I play, the fan on the video card does not spin up when things get intense on AVWW.

That doesn't sound like a heavy graphics load; that sounds like a CPU drain, then. Has this been an ongoing thing, or is this new?
Is it just the first time such a new attack is launched, or is it every time during the fight? It could be a stutter from disk loading (there's a settings option right under the one for the FPS display that lets you see disk loads during gameplay). Not sure, but that might be it.
