Cannot play Diablo III fullscreen smoothly on TouchSmart 520-1070

[hellarch]

I just recieve the All-in-one TouchSmart 520-1070 yesterday. The performance is so bad when I play Diablo III on fullscreen 1920x1080 mode, even if I turned everything lowest, there is still 200-300ms delay on every action I did. Can't believe it is a $1200+ computer.

Sorry, to hear about your issue. The HD6450A discrete MXM graphics in your HP TouchSmart 520-1070 Desktop Computer isn't a gaming class graphics sub-system. Please review AMD All-in-One discrete graphics solutions for the the specs of the low-end HD6450A and those that may be better as gaming.

FYI... All-in-Ones and TouchSmart Desktop type computers aren't really designed for gaming as are a very compact assembly with low power requirements. These computers share more with laptops, in design and construction, than they do with traditional desktops.

Is there anyway to improve it?

My friend has an 25' iMac with

• 2.5GHz Quad-Core Intel Core i5
• 1920 x 1080 resolution
• 4GB (two 2GB) memory
• 500GB hard drive1
• AMD Radeon HD 6750M with 512MB,

All the specs looks lower,  but runs good...

The only way to improve it would be to replace the existing MXM card with a more power card. Contact HP and see if they have any of these MXM cards that are compatible with your computer;

HD 6650A, HD 6670A, HD 7670A, HD 7650A, HD 7470A

Please note that replacing the current card with a new one is an extreme undertaking. It is like working on a laptop.

Again... the graphics sub-system is what is making the difference;

YOURS

AMD Radeon™ HD 6450A Graphics

625-750 MHz engine clock
533-800 MHz DDR3 (1.066-1.6 Gbps) or 800-900 MHz GDDR5 (3.2-3.6 Gbps) memory clock
8.5-12.8 GB/s (DDR3) or 25.6-28.8 GB/s (GDDR5) memory bandwidth
200-240 GFLOPS Single Precision compute power
TeraScale 2 Unified Processing Architecture
 160 Stream Processing Units
 8 Texture Units
 16 Z/Stencil ROP Units
 4 Color ROP Units

HIS
AMD Radeon™ HD 66xxM / 67xxM Graphics
500-725 MHz engine clock
800-900 MHz GDDR3 (1.6-1.8 Gbps)  or GDDR5 (3.2-3.6 Gbps) memory clock
25.6-28.8 GB/sec (DDR3) or 51.2-57.6 GB/sec (GDDR5) memory bandwidth
480-696 GigaFLOPS single precision compute power
TeraScale 2 Unified Processing Architecture 
 480 Stream Processing Units
 24 Texture Units
 32 Z/Stencil ROP Units
 8 Color ROP Units

Your friend's graphics sub-system is two to three times as capable as your's. All other specs are relatively close.
