some question about 3d test

[butterflylcl]

hi,we have tested burn in 4.0 under the vista OS(CPU Math,RAM,ODD, audio, 2D,3D all set as 100% loading),and we found the score of "3D Test" on the windows was not very stability(some times higher than 300fps ,but some times shows just about only 30fps),so what reason may be cause the phenomenon?

waiting for your reply.tks.

We don't support BurnIntest V4 under Vista. You need V5 or the new V6 beta.

Also BurnIntest is not a benchmarking product.

We suggest using PerformanceTest if you are interested in benchmarking.

you are right,but we doubt that if any K/P could affect the 3D test while burning, because we loading so many test items.
