Yes it's true
Everybody already knows that GPU in PS3 is only slightly upgraded midrange GF7600GT taken from PC at the last moment when it came to light that projected 2xCell PS3 with no GPU would mighty su*** compared to X360.
128bit 8ROP 500Mhz 256MB DDR3.
Only pixel shaders were doubled from 12 to 24.
Thats why custom built GPU in X360 being newer technology (nearly DX10 card) beats it in most cases.Framerate on PS3 ports sucks like in

"Simply put, the PS3 doesn't hold a candle to the visuals found in the Xbox 360 version -- especially considering the handful of bugs that have dead soldiers getting stuck in walls and twitching on the floor. The detailed environments and clear draw distances aren't found on PS3. If you had never seen the other versions of F.E.A.R., you still wouldn't be impressed with the PS3's graphics, but compared to the PC and 360, this version is graphically dead in the water."
Also framerate problems!
http://www.1up.com/do/reviewPage?cId=3158930"First among F.E.A.R.'s transgressions is the nauseating framerate. This isn't me being metaphorical here; the framerate in this game is so bad that it literally made me feel nauseated after any appreciable playtime. We're talking about something in the realm of 20 fps; that's just inexcusable for an FPS. This isn't the kind of thing that only graphics snobs notice; this is a genuine, game-affecting problem.
What's worse is that, as a result of this, there's a perceptible lag between hitting the fire button and bullets actually coming out of your gun. And we still haven't exhausted the game's experience-killing technical issues; there's also a frequent audio glitch that periodically makes it impossible to determine what direction shots are coming from. This is fairly important information in an FPS, you know. And then there's the online play, which offers some interesting gameplay modes and a nice selection of levels and game options...and then shoots itself in the foot by providing no means of communication with your teammates whatsoever. No, not even in the lobby. No, not even preset phrases. I mean, really. What the hell?"
Enchanted Arms
http://www.1up.com/do/reviewPage?cId=3159298"Graphically, the Xbox 360 version wins. The characters look a bit sharper on the PS3, but the lighting looks washed out, and there are even issues with bumpy framerates and graphical pop-up when exploring larger areas -- and there are a lot of large areas in Enchanted Arms. Also, the Xbox 360 had online aspects, whereas the PS3 version does not."

Tom Clancy's Rainbow Six: Vegas
IGN:
http://ps3.ign.com/articles/799/799830p2.html"One area that Rainbow Six: Vegas on the PlayStation 3 does fall a little short on when compared to the other versions is with regards to visuals. It's a nice looking game to be sure, but the whole thing doesn't look quite as sharp as it could. Colors are a little duller and there isn't as much use of certain effects, like bloom lighting and such. Some folks may appreciate that aspect to a certain degree, but beyond that it still doesn't look quite as nice as what we've seen previously. Some texture work isn't quite as sharp, and the characters aren't as detailed as what's found in the 360 release, especially in the faces. Weapons that have been dropped pop in and out of view as you approach and walk away when they're but a mere 50 feet or so away.
Also, as we've mentioned in one of our last previews of the game, there's a weird issue when running the title in 1080i as everything, including the menus, look very blurry. It's pretty sharp when played at 720p, which leads us to believe that at 1080i the game is still rendering at 720p and then upscaling the output image to 1080i, but poorly." etc.
