Package: bzflag Version: 2.4.14-1 Since I upgraded nvidia-graphics-drivers to version 390.59-1, bzflag seems to prefer libllvm opengl support instead of Nvidia's hardware acceleration. It says OpenGL Driver: llvmpipe (LLVM 6.0, 256 bits) Its unplayable slow. Other games (e.g. tuxracer) are fine. Regards Harri
