Hey guys. I'm gettin a little p'd off with what looks like some kinda built in Interpolation. It seems any emu that uses Directx, the picture is filtered. This usually happens in any windowed resolution and most resolutions other then 640x480 DR full screen. I have attached 2 pics. The first one is of Nnnester running on my GeForce 2 MX. And the second pic is of the exact same emu running on my Voodoo 3 PCI.

I don't know if you can tell from the pics but I know my Voodoo produced clear, sharp images at all resolutions including Windowed ones. And the GeForce just spits out some kind of Interpolated, blurry image. Please help, this bluriness is driving me crazy and giving me a headache.

Keep in mind I have NOT enabled any filtering of any sort either.

You should know this, i think it's been explained to you tons of times. :p

nVidia cards use an overlay when hardware directDraw is used. A way to disable it is to completely disable DDraw HW Acceleration, but that can be annoyoying. :p

I know but there must be a way to get rid of the stinking overlay without disabling acceleration. Sorry for asking again....:( My bloody Voodoo 3 never had this problem and NO I don't want to use it instead.

Esturk, I'm not real knowledgeable about things like this, not like Chris Ray and Demigod are, but I've been told that all Nvidia cards do this blurring. All of the cards from the original GeForce to the Geforce TI 4600 do it. AFAIK, there is no way to get rid of it either. If you use the Geforce 2 for this emu, you will just have to live w/the blurriness. If I am wrong on this, please feel free to correct me anyone.
sincerely,

Eh.. like i said in my above post, he can disable DDraw HW Acceleration thru DxDiag when he plays. :p

Yeah. That should do it. Thanks Cooliscool and sxamiga! And sorry for asking such a dumb question again.:D Makes me wonder why Nvidia would enable such crappy overlay?

No problem. :)

I imagine they implemented the feature to improve upon pixelation, but many gamers prefer the natural look, myself for an example. ;)

I remembered my Voodoo3 and how it looked on the Snes, Honestly I prefered the filtering when I applied Glide to it. I'm not sure how snes emulation looks on a geforce. I honestly have not uses snes9x in so long

I think pretty much all Nvidia cards, starting from the TNT (possibly even the Riva 128) and onwards do DirectDraw filtering. Some ATI cards do it as well (e.g., my Radeon 9000 Pro). I don't think there's a way to turn it off either, unless you disable DirectDraw acceleration (as cooliscool pointed out), which I don't recommend, as performance will drag significantly. Disabling DirectDraw will also disable Direct3D and AGP support.

Maybe because 3DFX decided not to add it? :emb:

3Dfx was never known to be on top of the latest API technologies. To them it was Glide or nothing. They only included DirectDraw, Direct3D, and OpenGL (miniGL anyways) support because it was necessary. DirectDraw is supposed to have that filtering on, it's just 3Dfx didn't care enough about the API to implement it.

I myself found that pretty good, but since u dont like, heres what happened to me once:
I was running Gens-sega cd emu- and was just messing around with the options. I never use V-Sync for anything, but i just wanted to try to see what looks like.
The thing is that when i turned on v-sync, the blurry-DDraw thing disapeared!!!
It went back to the way my old Voodoo 3 did!!

Maybe u can try that. notice i did that on the emu, not on the GF settings. and i was able to reproduce the error. the strange thing is that now Gens doenst filter ddraw anymore.....

And my friends GF2 mx 200 doenst do it at all!! ive messed around for sometime, and couldnt make it work on snes9x. Strabge indeed!!!

Hope this help u out
