First of all, let me say that Imgur has horribly compressed the image quality.
For the performance: I am on a laptop with
- CPU: i5 M520 (2.4GHz)
- RAM: 4.0GB
- GPU: ATI FirePro M7820 (1GB VRAM)
and get about 15 FPS
The scene you see is part of a very big (15 * 15 areas) world with default settings. For this screenshot, I reduced the DrawRange to 200, the rest is hidden in fog anyway. There is also a huge lake surrounding the area.
It doesn't really show that well in the foreground of the picture, but the ground is covered with grass, bushes and ferns.
I only placed objects around the area of this screenshot. The rest of the world is empty.
The shadow map size is set to 2048 and all other shadow settings are maxed out. Grass range is set to 80.
I'm not too unhappy about the FPS, since it's an old (but still ok) laptop. I think I would like to make some sort of benchmarking scene out of this, just like the sci-fi demo from Esenthel since I would like to know the performance on other people's PCs. I would love to make a game with scenes like this, but I don't know on how many PCs this would run well (including dedicating parts of the performance to Game/AI/UI code
)
