[2008] Graphics Test. Looking for results from Vista users. Use Post # 39 attachment. -

I recently upgraded to Vista Business from XP Home. I found that my Visual Basic 2008 graphics applications is running much much slower in Vista than it was in XP. I took a small piece of my application and created a test program. I've set my computer up for dual boot so I now have XP Home and Vista Business on it. I've run my test program from both OSs and the results are tremendously different.

I have a custom built computer that has a Microstar Int. KT6 - V mother board. It has an AMD Athlon XP 3200 + 2.2 GHz with 2 GB RAM. It's a 32 bit processor. I do have the 32 bit version of Vista installed. I have only PCI slots and one AGP slot on my mainboard. I'm using a NVIDIA GeForce2 Graphics card that I bought back in 2005 with 32 MB RAM. My Vista Experience Index subscores are as follows:
Processor : Calculations per second - subscore 3.6
Memory(RAM) : Memory operations per second - subscore 4.2
Graphics : Desktop performance for Windows Aero - subscore 1.9
Gaming Graphics: 3D business & gaming graphics performance - subscore 1.0
Primary hard disk : disk data transfer rate - subscore 5.3

The test program that I created runs 3 screens that are the same except for the pen thickness. Screen 1 uses a pen thickness of 1. Screen 2 uses a pen thickness of 2 and screen 3 uses a pen thickness of 8. When I run the Graphics Test program my results from XP Home on my computer are as follows.
Screen 1 duration = 7,781 milliseconds or 7.781 seconds
Screen 2 duration = 7,796 milliseconds or 7.796 seconds
Screen 3 duration = 7,796 milliseconds or 7.796 seconds

All pretty much the same.

From Vista Business my results are as follows:
Screen 1 duration = 119,062 milliseconds or 119 seconds - Pen Thickness = 1
Screen 2 duration = 20,234 milliseconds or 20.23 seconds - Pen thickness = 2
Screen 3 duration = 21,609 milliseconds or 21.6 seconds = Pen thickness = 8

Usually when the pen thickness is lower the drawing is quicker but my Vista results show something very unusual happening. When the pen thickness is 1 the drawing is 6 times slower than when it is 2. The drawing is about 15 times slower in Vista than in XP when the pen thickness is 1.

I'm going to attach the program I created and someone can let me know if they were able to install it and run it from the attachment. If you run it let me know your results if you run it from Vista and let me know your computer set up. What's all the goods on your computer. What kind of graphics card do you have. Is it PCIexpress, PCI or AGP.

Next post will have attachment.
