Very simple... when u select 8xAA in crysis.

For ati it loads 8xMSAA

and on nvdia it loads 4xMSAA & 8xCSAA.. its Nvdia trick... they spend a lot of money to make game developers support NV

You will find a file called FSAAProfilesDX10.txt and FSAAProfile.txt in config folder.

Delete both files and then you will notice, both cards will use MSAA

After deleting that file, you will not see 8xq 16x or 16xq

Even for Nvidia will only get 2x, 4x, 8x, which is real 8x MSAA.

now compair with ATI.

when that file is there. when you select 8x it lodes 8x msaa for ATI and lodes 4x msaa for Nvidia....


not only crysis... even in CMR grid you have simular file....

Can you tell us where we can find this file please? I would try the trick... personaly i dont put AA in crysis i put the game at VH and the resolution at 1600x1200

No doubt crysis is optimized for Nvidia cards, my sapphire 2x3870s cards in crossfire struggle in windows x64 to give me 28fps at 1680x1050 with everything high and of course antialiasing off. I got 22fps with the same config at 1680x1050 with very high settings in window vista x64.

My friend with XFX 8800GT can easily get 28fps in vista with everything at very high at 1680x1050, wtf ??? and he has a core 2 duo e6700, 2GB ram, but his 8800Gt is a factory overclocked card from XFX but anyways what the hell my system is superior to his in every way????

It's only one game and not a very good one at that. Shouldn't be cause for concern.

im actually hooked to that game, even with my 1ghz hd3870, it still struggles to produce reasonable framerates, not to mention im in 12x10

hi m8... nice to see you..

Its inside.. Crysis\Game\Config

There are two files

For DX9 the file is FSAAProfiles.txt


And for DX10 the file is FSAAProfilesDX10.txt



The original file is says this


Version (1.00)

DeviceGroupID 'NVIDIA'
{
VendorID = 4318 // NVidia
Devices
{
MinID = 0x0000
MaxID = 0xFFFF
}
}

FSAAProfile 'CSAA'
{
DeviceGroup = NVIDIA
Mode
{
Samples = 4
Quality = 8
Desc '8x'
}
Mode
{
Samples = 8
Quality = 8
Desc '8xQ'
}
Mode
{
Samples = 4
Quality = 16
Desc '16x'
}
Mode
{
Samples = 8
Quality = 16
Desc '16xQ'
}
}


My edited version for ATI is


Version (1.00)

DeviceGroupID 'ATI'
{
VendorID = 4098 // ATI
Devices
{
MinID = 0x0000
MaxID = 0xFFFF
}
}

FSAAProfile 'CFAA'
{
DeviceGroup = ATI
Mode
{
Samples = 4
Quality = 0
Desc '4xMSAA'
}
Mode
{
Samples = 8
Quality = 0
Desc '8xMSAA'
}
}

FSAAProfile 'CSAA'
{
DeviceGroup = NVIDIA
Mode
Mode
{
Samples = 4
Quality = 0
Desc '4xMSAA'
}
Mode
{
Samples = 8
Quality = 0
Desc '8xMSAA'
}
}

To check the settings, after applying AA, click on ~ key for opening the conaole and it will say

FSAA = 1
FSAA_sample = 8
FSAA_quality = 0

And if sample is 4, then 4x AA and if the sample says 8, its 8xAA-- which is pure MSAA. now ready everything is ready.......

My edited version will make Nvidia use the original MSAA like ATI card

AND TO ADD GPU IN THE GPU LIST

Edit the file amd.txt which is inside Crysis\Game\Config\gpu

Add the following line if you are using New ATI cards

0x1002, 0x9441, 4 // ATI Radeon HD 4870 X2
0x1002, 0x9440, 4 // AMD Radeon HD 4870
0x1002, 0x9442, 4 // AMD Radeon HD 4850
0x1002, 0x9508, 3 // AMD Radeon HD 3870
0x1002, 0x9504, 3 // AMD Radeon HD 3850
0x1002, 0x950F, 4 // AMD Radeon HD 3870 x2

After you add these lines... when u click on optimize the game.. you will get very high as default setting for all x2's and 4800 series........


Have fun...

It is.. and the Physx also plays a major role in other games... hmm.

the correction tweak will not give extra FPS for ATI, but will make Nvidia card show its real power

It give the actual FPS for Nvidia cards... and u will see 8800GT struggling in 8x AA. because when you select 8x AA without the correction tweak in Nvidia card. it uses 4 Samples which is 4x AA and 8x CSAA which is actually a trick... its not real AA

Lot of games in the market dose the same thing.. one other game is GRID. there are two files called hardware_settings_config.xml & Hardware-Settings-Options.xml and there you have same trick... and other files too


And when we do benchmarking. we should check using the MSAA to check the performance of the card. not CSAA or CFAA

CSAA nvidia
CFAA ATI

I tried this on my friends Nvidia and the first test was

Very High
8x AA which was using 4x sample and 8x quality
1280x720 and got 32 FPS

the same setting after using my file gave only 17FPS... he was shocked and started saying no i cannot accept this.. my card has a new technology and that is CSAA.. hehe

WHEN ONE CARD IS USING MSAA THE OTHER SHOULD USE THE SAME RIGHT

we cannot do racing with one car being a petrol and the other running in diesel

Crysis doesn't use physx, they have their own physics engine which utilizes the CPU to do the work.

ATI vs NVIDIA --------


I didnt mean physx in crysis.. but in other games..

Ya i made a mistake and corrected it

I typed "It is.. and the Physx also plays a major role... hmm."

I added "It is.. and the Physx also plays a major role in other games... hmm." and now its right...
