is that cheating? lower visual quality for higher fps numbers?
The visual impact is only when first entering an area. The texture quality equals out over time. It's the discrepancy in the amount of time it takes to reach the highest quality which is the issue that he brings up in the video. It probably relates to how the megatexture stuff works in the idtech engine.A better question is will overall performance drop once the bug if fixed. Either way the effect is ugly how have reviewers not noticed this?
I can't tell you why this behavior is occurring but I doubt it will affect performance for the reasons mentioned. I swear half the people in this thread didn't bother to watch the video or don't understand how the idtech engine works. It's not that there's an image quality discrepancy per se but there's an issue on Nvidia cards which causes the megatexture's to stream more slowly than on AMD cards.
