Intel 82865G Chipset Blit scaling method?


My question has to do with what kind of scaling the Intel 82865G Graphics Controller will perform when issued the Blt() command with C++ using DirectX 8.1.

Generally referring to this MSDN Article:

as well as comments in this thread:

How to report bugs in OpenGL drivers for Intel based video cards..

We have a number of users complaining about OpenGL artifacts and other problems when using Intel chip based video cards ( such as shipped in various new Dell configurations). I cannot find any link on the Intel site to report bugs with these cards/drivers. How do I contact the responsible people?

Multi-Resolution SDK


I'm trying to develop a plugin for 3D Studio Max 6.0 that utilizes the MultiRes feature. I have the 3dSMax SDK, but after contacting them, they instructed me to contact Intel (since they developed the technology). I can't find a support email (that doesn't cost money)... so could someone point me in the right direction as to who to speak to? Or better yet, does anyone have experience programming with MultiRes? I need to know how to 'drive' MultiRes programmatically.

Thank you,

Q&A: Speeding up a CRC32 Algorithm

Here is a question received by Intel Software Network Support, along with the response provided by our Application Engineers: Q. I'm trying to build in some assembler code into a C++ code to speed up an CRC32 algorithm. I currently have the lookup table generated and Im trying to optimize the following function: DWORD crc32(LPCSTR *s, unsigned int len, DWORD dwLastCRC)
{
DWORD dwCRC32 = dwLastCRC;
unsigned int i = 0;

for (i = 0; i < len; i ++)

Approximate math library for Linux? Or exp function algorithm?

Hi,

I'm working on a project for which I need a very fast & vectorizableapproximation of the exp function, accurate to say 0.1% or so. I've tried to use the approximate math library, but that appears to be Windows-specific. (I did hack around a bit and get a version that would compile, but it causes a segfault sometime after the am_exp_ps call returns.)

Would anyone know if a) there's a Linux version around somewhere; b) what needs to be done to convert the Windows code; or c) the source of the algorithm used, so I can code it myself?

Thanks,
