Ladies and Gentlemen ever since the release of the PC version of GTA IV we have been here scratching our heads and wondering why FSAA was never supported. Well fear not PC gamers, because Some Dude from 3d Center forums has created a hack which makes FSAA (FXAA) possible for GTA IV.

GTA IV NO FSAA


GTA IV FXAA BETA 4

Hows the performance with FSAA?

Edit:

Any image with a white box around the minimap does not have FSAA effect applied.
Taken with maxed settings at 1200p, 7th patch. It sometimes throws an error out while starting but sometimes the game will load anyway. Causes a black screen, you pretty much have to guess to load the story. Once the game loads, it works fine. Slight performance loss.

FSAA is not the same as FXAA. If you were using proper FSAA you would lose alot more frames, but get better results on non-alpha surfaces.

FXAA is a newly developed postprocess-based algorithim, just like morphological filtering. All it does is blur the hard edges of the scene and produces fair results for little performance hit. And it works with games that implement deferred shaders.


Also, incase you didn't know, BETA 6 is out:

I'm not having much luck with this.
With BETA 5 my frame-rate is reduced to 1, and with BETA 6 my frame-rate is reduced to 1 and this happens:

Beta 8. I'll see if this changes anything.

It fixes the black loading screen + menu problem, but it still slays my performance.

@Mealing: What graphics card are you trying to use it on? Have you updated your drivers? FXAA is pretty new Nvidia-developed technology.

[Mealing]

I'm using a GTS 250 with 275.33 drivers, although I've read that people can use it with AMD cards and even Intel chips.. which makes me think that the FXAA is done via CPU rather than GPU.

Full specs anyway:
Q6600 @ 2.4Ghz
2GB RAM
GTS 250 (512mb)

-edit
Beta 9! I'll give this one a go with some different games as well.

-edit 2
Fallout 3: Didn't seem to do anything at all, looked jaggy all the time
San Andreas: Worked perfectly, lost about 4fps.
GTA 4: Unplayable.
Assassin's Creed Brotherhood: No loss of FPS (although it's capped at 30), works perfectly.
MoH: Minimal FPS loss, looks fit.

Both brands produce cards that are capable of both morphological & FXAA. However they have copyrights and were developed (or are owned) by the brands respectively. It's the same with PhysX, Nvidia just doesn't want AMD to have it. FXAA source code has been released by the developer himself (probably with Nvidias consent though) on his blog, which is why everyone can use it. Think of it like the blur filter on GTA4 - any card can enable this right? It's essentially the same rendering process.

I have noticed that it uses a little bit of CPU, but it shouldn't be a problem on most games especially if you considered overclocking. It might be that you are exceeding your video memory by enabling it, so make sure to leave some graphical headroom before turning it on.

Works fine on ATi

This is great..a real improvement to GTA 4. Thanks!.. especially to the developer.

I've tried fiddling around with my settings a bit and I can finally get decent frame-rates.
Unfortunately I only get them when I run the benchmark, actual gameplay is still stuck at 1fps.

I always knew the benchmark tool was a bit funky, but that's just weird.

same problem!
also have gts250 512mb
full spec: athlon x2 6000+
4gb ddr2 ram..
upd! when i change resolution to 1024x768, 1frame problem disappeared...
video driver is 280.26....
btw FXAA works fine on iCEncancer 1.3, but i wont use FXAA without Enb...
help please!

So does GTA IV on Windows 7 use Direct X 9 or Direct X 10? I think Ive got Direct X 11 so I'm not sure about which one to use.

[luceberg]

GTA 4 is a DirectX 9 game, so use that one.

[nkjellman]

Thanks. But when I have this in my game performance seems slightly better, but that could be because I recently fixed some PC errors with Advanced System Care. But anyways this does the same thing that FXAA does for enb series. It seems that some things are less jaggy but other things are not effected and are still jaggy.

[luceberg]

It just smooths out the jaggys a bit. It makes playing the game easier on the eyes for me anyway.

[nkjellman]

Yea, someone linked me to this mod before (different topic) and I thought it was just for enb because the dll was a different name and I had to enable it in the enbseries.ini. But that was so this would work with enb it turns out. But I will say that this does not hurt my FPS at all, if not increase them.

Does this work on ATI cards?

[Mealing]

Little bit of a bump but after experimenting a bit I've found that the FPS drops only occur when you're in an interior or an area with different lighting.
I'll try and see if I can tweak the settings so it's fine throughout the game.

Also it works fine on ATI cards.

five months without a new post, any news about this FXAA ? what's the last version and where i can find it ? it's worthing ? thx !
