Intel has been planning on releasing a driver that will allow DX10 on some of its integrated video solutions for a while now, with some people expressing frustration over the wait. It has been clear recently that NVIDIA has been taking the aggressive approach when commenting on the performance of Intel IGP products and today seems to be no different. In an email from NVIDIA doing the rounds they raise questions about DX10 support on Intel chipsets and cite some leaked beta drivers to show that performance won't be up to scratch for those interested in DX10 games titles. They quote rates below 5fps for games such as Crysis, Bioshock and World in Conflict at a resolution of 1280 x 1024 with no AA/AF. Obviously claims made by direct competition need to be taken with a pinch of salt, but it seems as though NVIDIA isn't going to let up in the criticism of Intel's graphics performance (while offering you some alternative products of course).
