I haven't the slightest what could be causing it. Doesn't seem to be limited to one game, as it's happened with several games.
1. Dolphin works and performs best on a modern OS (Windows 7 64bit or Windows Vista Service Pack 2 64-bit). Avoid legacy/unsupported operating systems such as Windows XP or Linux distros with crappy drivers.
2. Make sure you're using the latest drivers for your graphics card (download GPU-Z from
http://www.techpowerup.com and post a screenshot).
Uninstall the old drivers using AMD's uninstaller (Control Panel -> Programs and Features -> Catalyst Install Manager -> select 'Express Uninstall all AMD software'), restart the PC , install the latest official driver (Catalyst 12.4 WHQL) from
http://support.amd.com (
http://game.amd.com) and do another restart.
3. Grab the latest version (GIT build) of Dolphin from the Dolphin download page (currently at rev. 601) and extract it to a New Folder on your hard drive.
Use the the default / recommended settings. Do not copy / import configs from older versions of Dolphin. Enabling settings such as 'DSP LLE on thread' or 'JITIL experimental recompiler' can introduce instability / crashes.
4. Extracting OpenGL .DLL files from
old drivers (Catalyst 12.1 or older) to the Dolphin folder (or any other folder on your hard drive) is not recommended. WIth a HD7000 series card you're guaranteed to experience issues such as warped/broken graphics or a very noticeable drop in performance that sticks until you restart your PC.
Old OGL DLLs work only with with older (HD2000 ~ HD6000 series) AMD/ATI cards.
5. If you're using Windows 7 or Vista, disable compositing (Aero Glass). Aero causes problems when running in windowed mode with VSync=ON, adds input lag, reduces the performance a bit and is known to cause GPU resets/BSODs with certain ATI GPU+driver+OS combinations.
First post updated with new tests and more info.

your card is in range of 4850 which is pathetic

there is your difference
with that card you shold be able to play at ~x1.5 scale maybe some weaker games with x2.5
but that's it
card sux badly
if you wish top performance you should ALWAYS buy at least X870 gpu series
meaning :
4870,5870,6870
OR above!5970,6970 etc
Never under X870
There are some beautifull benchmarks done by PCSX2 team,which is very good for reference when buying GPU

No. The HD7750 is capable of 3xIR and 4xIR in some cases.
PCSX2 is not the same thing as Dolphin (Dolphin uses the GPU in a different way).
Here's a quick benchmark I did with PCSX2:
Crash WoC Level 7 @ 1080p,
6xIR + bob (tff) deinterlacing ,
D3D11 backend , FPS measured with FRAPS
----------------------------------------------------------------------------------------------------------------------------------------------
HD5570 = 22 fps
HD7750 =
51 fps (47fps with the D3D9 backend)
The D3D11 performance in PCSX2 is
surprisingly good.

4xIR in every game (D3D9 backend), except SMG
(with Aero/DWM OFF and the resource hogging Catalyst Control Center not loaded at startup)
IcemanSR Wrote:This card sux badly.
If you wish top performance you should ALWAYS buy a much more powerful gpu.
The raw power of the card is not the problem, but something else (driver bugs, lack of optimization, memory management issues or maybe something to do with the different GPU architectures)
What you may find interesting is even a much more powerful card such as the Radeon HD6850 (32ROPs, 128GB/s bandwidth, 1.5 TFlops) still gets beaten by a low-end HTPC card (the HD5570).
How many times does this need to be said? IT'S THE DRIVERS.
IceMan clearly did not read the OP so there is no point in responding to him.
Same answer, so let me try a different way of writing it this time:
Code:
if (videoCard.Problem() == true && videoCard.Brand() == "ATI")
{
cout<<endl<<"It's the drivers fault"<<endl;
}

7xxx series = immature drivers, lots of nasty bugs, major performance issues
6xxx series = average drivers with a few annoying bugs and some performance issues
5xxx series = very good drivers, almost no bugs (except OpenGL), decent performance
Oh well

AMD Radeon HD 7770 And 7750 Review
http://www.tomshardware.com/reviews/radeon-hd-7770-7750-benchmark,3135-6.html
Quote:AMD’s Radeon HD 7750 doesn’t quite manage to post playable frame rates at either resolution using High quality details. Dialing down to the lowest settings would probably work, but if you really want to enjoy this title in its PC-centric glory, an entry-level card isn’t the way to go. A Radeon HD 7770 or a 256-bit GeForce GTX 460 would probably be my personal baseline.
And the WORST part is ,that 7770 is ONLY 40E more expensive then 7750
AND 6850 is SAME price as 7750
only up in price on 7750 is LOW power consumption.
One gotta be Einstein to make super rocketed drivers to make 7750 to work as 6850
