Hi,
The introduced changes improved my panorama video performance (I used following benchmark tool :
http://www.os2warp.org/sysbench/sysb095c.zip)
The performance are without video accelerator (panorama) and the result did a jump from 7.700PM with older GRADD.SYS to my best new graddd.sys benchmark of 166.000PM and most time above 145.000PM. This gain in performance is true for those having bad MTRR setting. For others, I don't know. Just do some benchmark test and compare results (my results are for a gforce 9600gt)
An older test using SDDhelp.sys in conjunction with Panorama and older gradd.sys didn't improve video speed on my I7 system but seemed to improve performance for other system. What I could read about use of SDDHelp was more like a bypass to bad performance with various results.
Cheers/2
Remy
note: It doesn't add wide screen support like previous one didn't.
