First test returns half the throughput, do two tests. May be caused by driver, may be some 'energy saving', will need to be checked later. It was working the same way prior to ExtraFPS, but viewer was running an extra CPU test. --- indra/newview/llglsandbox.cpp | 66 +++++++++++++++++++++-------------- 1 file changed, 39 insertions(+), 27 deletions(-) diff --git a/indra/newview/llglsandbox.cpp b/indra/newview/llglsandbox.cpp index 112008172e..5484ce6276 100644 --- a/indra/newview/llglsandbox.cpp +++ b/indra/newview/llglsandbox.cpp @@ -903,6 +903,39 @@ private: };
