Anti-Aliasing and GP4

I found out that AA is BAD for GP3. It slows the game to less than a crawl. My card has settings from lowest to highest: Application, None, On, 2X, and 4X for anti-aliasing.

What should I set it to , for best fps, and or best visuals ? What does it really do ?


JohnW

depends what card u have, if it is a top end card ie radeon 9700/9800 or high end nvidia one then putting AA onto 4X shouldn't make much difference. I run GP4 at full details, 1600x 1200 with 4xFSAA and 16x AF @ 40 FPS with my rig in the sig below

Thats a serious system my friend.

I have the following and run at same resolution and have PO of 70 at grid, which I think is good for my system.

Athlon 1900XP
Soltek N Force2 400
Sapphire Atlantis 9600 Pro
512 PC2100 DDR
2 x HD (20 + 40 GB)
LG 16 DVD
Plextor 48 x 24 x 48

GP4 is beautiful, fast and the vipers cars look superb!

Stupid question I know, whats AA and where do you turn it off??

JohnW: For best FPS AA should be off. It takes a lot of capasity from the graphicscard...


Definition: Aliasing is the jagged edges on curves and diagonal lines in a bitmap image. Anti-aliasing is the process of smoothing out those jaggies. Font smoothing software provides anti-aliasing for on-screen type. Graphics software programs have options for anti-aliasing text and graphics. Enlarging a bitmap image accentuates the effect of aliasing.

Left side of image shows aliasing or jaggies in the curved lines. Right side of image shows the effect of anti-aliasing to smooth out the jagged edges.




rayg: normally ypu can turn AA off in your graphic-card otions menu/ card setup menu

Couldn't dream of it with my old gef 3 ti200. With Radeeon 9700, the aa at x4 and af at x16 makes no difference to fps. I run at 33 fps 1280x1024 everything maxed except em on static. Looks divine
BTW not all games like the aa and af settings. eg F1C suffers alot, I lose 50% of my fps with aa and af on.

My card is a NVidea gForce 3 Ti 200 ( 64Mb )

You can adjust the AA under the display control panel. Then Advanced, then choose the NVidea tab.


JohnW

howdya get that running so sweet beardless, ive got a 2800xp and 9800 pro, and ive got everything on high on 40 with 1024x860 with no aa or af

Hi Fongu,
read above. It's about your graphics card, not the processor. Basically, if you have a really good card (radeon 9700/9800) you can switch on the aa and af without pushing the cpu at all.

fongu, AF or AA should make hardly any performance hit to ur system with the 9800 pro - then u will be same as me

anyway johnW, as u only have a ti 200 (which isn't exaclty bad) i would say to leave AF and AA off - this is because it doesn't have the "grunt" of modern cards to not take a significant performance hit

yeah i get that, but i am talking about the processor, im sure i can get more out of my processor, any ideas?

Probably not, cos GP4 needs so much processor power. If your CPU needs to help produce aa and af, then your occupancy will go up and game performance will go down and everrrrythiiing wiiilll geeettt realllly sloooooooooow. And that, my dear fongu, is why you will need to invest in a top card (I recommend radeon 9700 pro or 9800). Then you will notice abig difference. BTW your sound card also has an effect. if your sound card doesn't take work load off the CPU this can slow you down too. I was desparate and one stage with my fps down to 19 and below and po God knows how high. Sound card and a little tweaking of Bios memory settings fixed it.

Yeah i do have a radeon 9800:P (with omega drivers). But yeah, the sound makes a lot of difference. Im only using onboard sound at the moment with 5.1 surround speakers, but i turn off the hardware acc, and use just 2 speakers, and its still just 40fps, with it on its more like 34ish. So im still not sure about how much performance im getting off my processor.

Try upping your memory performance settings in Bios. I have mine set to turbo. I don't have stability problems- although Gp4 does CTDT on occasion.Hard to say why. In any case you should be getting more performance. I would suggest a decent sound card then. Did you read this thread:

DuMaSs had really low fps before installing his new sound card.

Yeah, i'll look into that. Being the cheap student that i am, i spent ages saving up for the other bits, so it'll be a while before i get a soundcard.

On the bios thing, what dya change, ive changed my fsb (or something like that) from 100 to 166, which apparently is max before overclocking. Im not too keen on overclocking whilst the comps still fairly new. Its still running pretty hot, at about 69degrees most the time, so i'll have to look into getting more fans! Thanks anyways

It's not that simple. I don't oc my cpu but if you change the fsb you have to change the other setting. Damn, I've forgottenwhat it's called. Anyway when you multiply the fsb by the other number it should equal your CPU ghz level. If it's more you are overclocvking. The thing which has most effect seems to be memory settings. My Bios have ready made settings: optimal/agressive/Turbo/expert. Expert means you change the settings manually. Otherwise they are automatic and are greyed out. I am using turbo, but aggressive is oprobably good enough. Maybe turbo is creating occasional instability. Difficult to say. I used to think i understood this stuf, but ....

Yeah thanks for that, just scrolling through some forums at the moment, looks as tho im running it at pretty much max, and apparently quite hot as well. Thanks Larry

Guys, PO is nightmare that I've been having since I have GP4, my aspects now a days is AMD 2200+, RAM 512MB DDR, Nvidia Geforce FX 5200 128MB, HD 40GB 5200RPM, due to a compatibility problem between MS sidewinder and Sound Blaster 5.1live, I am using onboard sound card. My fps is 27 with no mirrors and 800X600X16, I can't believe, my PO goes from 35 to 135 depends of the quantity of cars close to me. Interesting for example, when I am in the starting grid let's say in sixth place in Monaco my PO is 75, but when stars my engine PO goes to 98, I didn't know that sound increases PO, in resume I've been fighting against PO since long time and I am always the looser.
