All,
I have a need to run my OSG app on some "marginal" hardware (single CPU with a GeForce 4800 for example) while still maintaining some decent frame rates (around 30fps). I want to use the same terrain database (built with VPB with the -terrain option) if possible. I've used the setSampleRatio() method in the osgTerrain class and culling backfaces to thin out the geometry with some success but I'm still not where I need to be. As a result, I'm wanting to optimize a bit more if possible. Does anyone have any suggestions for particular settings in the databasepager or pagedLOD that I could try to achieve better performance? I'm willing to sacrifice database fidelity to maintain decent frame rates if I must. Thanks for any suggestions in advance. Shayne
