OpenGL Frame Latency / Jitter Testing On Linux
Phoronix: OpenGL Frame Latency / Jitter Testing On Linux
Beyond there finally being Team Fortress 2 benchmarks on Linux, at Phoronix is now also support for OpenGL frame latency benchmarks! It's another much sought after feature and request for graphics hardware and driver testing...
I have questions about how this works
On the windows side, we've been told it's impossible to capture this information reliably without a piece of dedicated hardware that NVidia recently released to some review sites. This seems to be completely in software, though.
Is this going to run into the same issues that windows games had? Is it the same less accurate tests that came out on windows a while back, that can show some obvious problems but not the real details of what's going on? Or is OpenGL somehow different than D3D in this regard?
