Why are Radeon HD 5750 and Radeon HD 5770 so weak in GTA 4?

They have 1 GB GDDR5 but offer less performance than GeForce GTS 250 DDR3 (renamed 9800 GTX+), not to mention the GTX 260.

GTA4 is a TWIMTBP game so right of the bat the Radeons are in a disadvantage. Second the GTS250 comes 256 bit bandwidth, that double the bandwidth of the Radeons and GTA4 really loves bandwidth. The 5750 has got a little bit less of everything, so it fall short of the GTS250, but the 5770 isn't all that far behind the GTS250, the fps difference being only 3-5. GTX 260 on the other hand is in a totally different class both in price and performance so there's no use comparing them.

This is just not true. Memory bandwidth is a combination of both bus width and memory speed. While the GTS 250 does have a 256 bit bus width it also uses DDR3 ram while the HD5750/70 use DDR5 ram. In the end the HD5750 has a memory bandwidth of 73.6 gb/s which is actually higher than the 70.4 gb/s of the GTS 250. Furthermore the HD5750s overall performance is in general slightly superior to the GTS 250 as well.

The Way It's Meant To Be Played - It's an Nvidia marketing slogan used in games which were developed with the assistance of Nvidia. Meaning that they were specifically designed to run better on nvidia cards, even though most of the times you wont see much difference, and ive seen some occasions when ATI cards actually better than nvidia in those games. It's mainly for marketing purposes, but it this particular game it actually holds true and nvidia does have an edge.
And to reply to jyjjy, my mistake, I did mean bus width there, but GTS250 generally outperforms 5750 despite what the numbers might say, albeit not by much, but that little advantage of the GTS250 is increased with TWIMTBP.

No they were not specifically designed to run better on nvidia cards. That is pure marketing

It's mostly marketing but working closely with developers can yield better performance on specific hardware, so it's not all just hot air. GTA4 is one of the best examples of a TWIMTBP game running slightly better on nvidia, marketing or otherwise.

The drivers are immature for 5770 and GTA4.

No it's not. Stop spreading mis-information. The 4870 is better than the GTX260 in GTA4, so it's not an Nvidia game. The 4870 gas a 256 bandwidth w/ GDDR5 and the GTX260 has 448 bandwidth with GDDR3.

1. were not talking about 4870s
2. 4870s are generally faster than gtx260s
3. I never said that just because it's a TWIMTBP game nvidias will always be faster, I said they have a slight advantage

If the bus width is not the reason to be slower , and Radeon HD 5750 has better memory bandwidth then what is the reason ?

Just because a game is hard to play it doesn't make it rubbish does it . Look at crysis - machines more powerful than your struggle to play it with frames +50 on high resolutions and yet the majority love it. d It's a bad port but It's still an amazing game with one of the most realistic free-rome cities I have ever seen.

Yeah, it's very poorly optimized port and is bad in that sense but otherwise it is fine.

Some of the new updates for GTA 4 have improved the game. There is a new shadow system in place, etc..
When they released Liberty City Stories last month for the PC
they released the patch and I can tell the truth that the graphics are that much crisper and better, and somehow I was allowed more resources for graphic options.
It incorporates the start of the games together and Social Club is no longer required for play.
