A performance bug in recent NVIDIA drivers has been causing a loss of performance across the company’s GPUs. Additionally, the bug results in higher VRAM usage than previous drivers, and NVIDIA has now commented on when the issue may be fixed. Thanks cageymaru.



This likely matches a similar performance drop observed on another Feral game, Total War: WARHAMMER. We’ve been tracking it internally as bug 1963500. There was a change, introduced in our r378 branch, to the logic of allocation of certain textures, but it apparently exposed a bug in our memory manager. Our next release branch, r390, will carry a workaround, and we’re still working on finding and fixing the root cause.
