Crappy 2D performance

[antareus 0]

Hopefully someone on the board has had this problem.

 

Obligatory hardware specs:

Athlon 800 on Asus A7V

256MB PC133 SDRAM

Creative Labs GF2 GTS

Win2k SP1

Det 11.01

ACPI on

 

So, um, I reformatted to turn ACPI on to idle a bit cooler degree-wise (shoulda saved my MP3s). Anyway, like 8 devices are sharing IRQ 9, per the silly ACPI spec, but I can't change any of them. In 3D games its fine, maybe even a tad faster. In Windows, 2D performance just blows. I see windows redrawing in front of me, its as if I'm using a pentium 133 with a crappy video card. It makes using the computer quite sluggish and frustrating. It never used to do this before, is it that damned ACPI?

 

I wish there was a way to force certain devices to have IRQs. The video card sharing an IRQ is just very stupid.

Been there done that. Ususally the best solution for your pc is to leave it if things are working well for you. For the A7V, make sure you have the 1007 bios--that fixes a ton of problems. One problem it was supposed to fix was an IRQ conflict between the Promise controller and PCI slot 2. If you have anything in slot 2, try to put it elsewhere.

Q. What is the status of 2D stretched sprite smoothing in the latest drivers?

Q. What is the status of auto mip-mapping in the latest drivers?

Q. Can I force a 16-bit z-buffer in the latest drivers?

They are all currently disabled, although there may be drivers released later that will support them.

 

In the case of 2D stretched sprite smoothing, this appears to have been disabled since the 5.xx drivers. You can see the effects of this in games like G-Police (beacons) and some SNES emulators.

This also happens in older cards (TNT series). Crapier cards, such as sis models, can do hardware stretch interpolation in their W2k drivers. You'll hape to cope with this "FPS drop when resizing windows in 2D games" until nvidia realizes 2D is also important.

I found that Win2K has crappy 2D acceleration by default install (under DX7 and IE). I recently did a new install and saw the same thing. When I upgraded to DX8 (now 8.1) and IE5.5SP1, my snappy 2D display speed returned. Not sure which is responsible or why, but both have code that is used to handle windows redraw on the desktop, so I recommend you update both of these two apps if you haven't already.

 

BTW I am running both GF2MX on one W2K machine (BX chips) and the GF3 on another (VIA dual) under the 11.01 drivers (like you) and I am getting excellent 2D performance on both, so it is possible!

 

Hope that helps,

ACPI on or off? I've gotten great performance w/o ACPI but of course I like having my Tbird idle cooler so I don't burn it out so fast ;(

I would recommend leaving the ACPI setting on if you dont have problems. Playing around with that has given me hell in several different configs, so I leave it be. If your smart you'll leave ACPI be...Win2k has full support for it, and MS, this may come as a surprise, does know what they're doing.

NO matter how many IE builds you install, or DirectX betas. If nvidia hasn't enabled hardware stretch interpolation in their drivers yet, this problem won't go away.
