Home Forums Discussions Problems Fixed!!!

Hi all,

I have posted numerous times over the last 2 weeks, very slow rxing c WinXPPro and AC v6. New video cards fixed desktops.

Today I got a call from Russell at AC tech support. He suggested turning "hardware acceleration" all the way off. (sluthra posted this last night, I did not get to try it yet.) So I turned acceleration off on one of the still slow laptops, and IT WAS FIXED!!!!!

An earlier post had suggested turning acceleration halfway down. I had tried that, with no change. So I experimented with different settings. With the lowest setting (off), or the next to lowest setting, essentially normal. With anything higher, slow and funny looking screen.

Thanks to Russell for calling, and to all who responded over the last 2 weeks.

Hopefully this is the fix for everyone that has that problem.

What is the procedure to turn off 'hardware acceleration'?

Here is the link from a previous post - http://sluthra.x10.bz/v6_tut.html

SO my old laptop won't upgrade to Windows 7. I did turn hardware acceleration off and it is 'usable'. When I ran Windows 7 Upgrade Advisor I learned the following:

"...Your current graphics adapter won't support the Windows Aero user interface. If you want to experience the benefits of Windows Aero, contact your PC manufacturer or retailer to see if an upgrade is available..."

alas, this is a laptop, no graphics card upgrades.

So I looked at the Windows Aero User Interface page
"...http://windows.microsoft.com/en-us/windows7/What-is-the-Aero-desktop-experience ..."

Show allAero hardware requirements
Your computer's hardware and video card must meet hardware requirements to able to display Aero graphics. Check that your computer meets the minimum hardware requirements for running Aero:

1-gigahertz (GHz) 32-bit (x86) or 64-bit (x64) processor

1 gigabyte (GB) of random access memory (RAM)

128-megabyte (MB) graphics card

Aero also requires a DirectX 9 class graphics processor that supports a Windows Display Driver Model Driver, Pixel Shader 2.0 in hardware, and 32 bits per pixel.

For best results, you might also want to follow these graphics processor recommendations:

64 MB of graphics memory to support a single monitor with a resolution that is less than 1,310,720 pixels (for example, a 17?inch flat panel LCD monitor that has a 1280 ? 1024 resolution)

128 MB of graphics memory to support a single monitor with a resolution from 1,310,720 to 2,304,000 pixels (for example, a 21.1?inch flat panel LCD monitor that has up to a 1600 ? 1200 resolution)

256 MB of graphics memory to support a single monitor with a resolution greater than 2,304,000 pixels (for example, a 30?inch wide-screen flat panel LCD monitor that has up to a 2560 ? 1600 resolution)..."


I have 384 MB of graphics memory and run 32 bit color on the graphics. I am running Direct X 9.0c. on an Intel 965 Chipset graphics driver. ---Frustrating.

Hope version 6.10 can avoid the screen redraw problems.

Graphics memory isn't a big indicator of performance. It's very difficult to tell which graphics cards are better than others based solely on specifications. Video memory is pretty much irrelevant. 1GB 5770 is worlds apart from a 1GB 6950. There's so much more that determines performance, i.e. number of stream processors. Type of memory DDR3 vs. DDR2 vs. DDR5, etc. Aero is just pretty visual effects like the transparent taskbar among other things. Disabling aero should boost performance.

Also, you currently do not have a dedicated graphics card. The Intel 965 is integrated graphics which is grabbing its video memory from your RAM.
