Size of textures and sprites in old 3d cards

Hi

It is known that old 3d cards doesnt render very well textures bigger than 256x256.
So in my game i try to make everything be 256 or less ( but my game is kindda big so everything has to be big) the problem is i needed a texture that has to be eg.512x512, but i dont wanna make it bigger than 256. So my question is:

IF I make a 256x256 texture and put it in WED and Scale it bigger by WED or by Code
does still gonna get problems with old 3d cards? ps. the original file is 256x256 i only scaled it by code or by WED.

another one:
Does this apply to Sprites? Can I have a 1024x512 sprite and still will render in old 3d cards?

thanks for you attention.

someone?

Scaling textures up should cause no problems on older textures.

Not sure about the sprites thing though. I think its the same as with textures.

"Scaling textures up should cause no problems on older textures."

did mean:

"Scaling textures up should cause no problems on older video cards." ??

Err... yeah, sorry about that ^_^

lol np
I just want to make sure of that, because i will need to make some smaller textures due to its size (megabytes) but my game enviromnent is big...so can I make my textures 256x256 ( to fit older 3dcards) and then just resize them bigger in wed and i should not have problems?

just making sure..

Correct.
Rescaling in WED = no problems.

lol
thanks ready!
