ISA video card is slow

By Mike (from Canada) ·
I have a computer that contains ISA slots.
I have windows 95 1st release and managed to enable DMA to my hard drive.
Windows accesses my sound card as well through DMA.

WHat I need to know is if it is possible to enable DMA on a video card. I want my games to run faster and as I am playing one, sometimes the page changes 1/2 a page at one time resulting in two halves. Its like moving a picture slowly on another. If it is the refresh rate that is the problem, then what refresh rate should Iuse? My display is configured at 640*480, 256 colors.

Please explain.

Its not the refresh rate - though you should put it up as high as your card will support. A low refresh rate shows a as a flickering.

The speed of your redraws has to do with the fact that you are on a slow bus (ISA) and that your video card memory is probably small, so it can't cache or buffer.

If your PC has PCI slots, try upgrading to a PCI card - the bus is much faster.

But it sounds in general like you might need a faster PC to be happy - are you playing games that fall into the "recommended" configuration or the "minimum"?

I agree with James.

If your computer has only ISA slots, it is at best a socket 5 pentium limited to 133Mhz processor. At worst, a 386DX system.

For under $150, you can buy used PII systems.
I have seen barebones PII starters for $20.
Checkout the systems page at www.compgeeks.com

If money is an issue, I recommend that you search the bargin bins for the best video card that will fit in your slots. If you have a VLB slot, some dealers are almost giving these cards away to get rid of them.
I would also recommend that you increase your system RAM. 30 and 72pin simms are still pretty cheap unless you go after the largest ones.

You might also get some improvement if the video card or chip mfg has a driver for W95. It may work better than the native W95 driver.
