Re: Crysis 2 DX11 Patch Live
The way Crysis 2 uses video memory is weird though. I had all my settings on Ultra in DX11 with high-res textures and saw it was using ~1500MB VRAM at 5760x1080.
So I turned off the high-res textures, and it was still using ~1500MB VRAM. I then turned all the settings on lowest and still saw the same VRAM usage. I then switched to DX9 and still saw the same VRAM usage. So I finally dialed down the resolution to 1920x1080, and only then did my VRAM usage go down, to ~1150MB! This was still with the same lowest settings and no high-res textures at DX9. This can't be right or people with 1GB cards would have seen terrible performance before, which wasn't the case.
So I'm thinking Crysis 2 just hogs as much VRAM as possible, and doesn't actually use all of the VRAM its occupying for at any given moment in the game, instead using the additional VRAM as a cache for other textures that aren't being used to reduce future loading times and such. OF course, with my original settings, I'm even amazed I get the performance that I do, barring the rampant popup and flickering of objects. However, its something I noticed even on my 6970 in my other machine at 1920x1080, and it also doesn't happen in DX9, so I'm thinking its something with the renderer.
