For now, I solved the issue by downgrading from the very new nvidia 440 driver to version 435.
Regards Julius From: ziegler Sent: Saturday, 19 October 2019 10:47 To: VirtualGL User Discussion/Support Subject: [VirtualGL-Users] Getting exactly 1 FPS on vglrun glxgears/glxspheres I have set up VirtualGL to run OpenGL applications on an Nvidia card through TurboVNC. I run lightdm display manager, and a mate-session. Based on what glxinfo tells me, the setup seems to be working: "OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 1650/PCIe/SSE2 OpenGL core profile version string: 4.6.0 NVIDIA 440.26" I now have the strange effect that basically any application (I have tried glxgears, glxspheres and my own custom code) that I run through vglrun runs with exactly 1.00 FPS (check the screenshot below). The CPU usage while running is negligible, so I assume that there is some artificial throttling happening, like some bogus VSYNC. One thing special maybe about my setup is that this is a rack mount server, which, appart from the discrete Nvidia card, also has an onboard VGA which runs GL via mesa, so this is a dual head setup. I separately tried VGL_SPOILLAST=0 VLS_SYNC=1 With no noticeable effect. Has anybody experienced this strange effect? Any ideas on how to solve it? Any hint is appreciated, Thanks!
