Diablo 3 is indeed a very well optimized game and runs without any problem on low end hardware. I manage to squeeze up to 55 FPS on low settings at 1280x720 with my Intel HD 3000 Graphics equipped laptop (Core i3 2310m CPU and 8 GB RAM), which is more than enough. I have played a lot with the video settings, but it was well worth it, as now the game runs perfectly smooth without any lag or overheating issues. I have written an article that explains the different Diablo 3 video settings and recommends the optimal ones for Intel HD Graphics and other low end video cards. If you are interested, you can check it out on my blog:

Diablo 3: Optimal Video Settings for Intel HD Graphics

9.5 for Diablo 3 score absolutely ridiculous. Totally makes sense though, once you realize he gave out the score without even finishing the game. "hint: he never even played in inferno mode"

My HP has i5-2450M 2.50 GHz, 6 GB DDR3 1333 MHz, Radeon HD 7690M XT, and a 1920 x 1080 display. What settings do you think I can expect to play D3 on?

Hey guys, will an Asus G75VW-BBK5 run this game on max settings ok?

Intel Pentium T400 Dual Core 2,3GHz / ATI Mobility Radeon HD 4650 1 GB .... What do you think guys ? :(

Diablo 3 runs quite nicely with Lenovo W520 (2860QM & Quadro 2000M) at 1920x1080 max details. Experience is not exactly butter smooth and lowering details doesn't really help so playing at max. With 4 players in group fps is good enough to enjoy this title fully.

Runs little bit better on my desktop Q9500 & GTX460M where fps is almost constant 60.

I ran diablo 3 on my lenovo t61 nvidia 140m 128mb at 800x600 with full group up to diablo with no issues
That was fun

Home rig
Amd II 3x 3.2 unlocked
Nvidia gtx 460 se overclocked 900core 2000memory

Will I be able to run with this PC? 

Intel® 2nd Generation Core™ i5 (2.5GHz (with Turbo Boost up to 3.1GHz))
NVIDIA GeForce GT 540M (1gb)

Sadly its hard to recreate intensive fights easily to benchmark them. It would be a lot of effort to do this. However, you should keep some headroom. For all users whose GPUs are not listed, just take a look in our gaming list

where all cards are listed according to the average performance.

This test is worthless.

Diablo 3 is capped at 60 FPS on my i7-860 3.5Ghz AMD 5870 solo, but I have even seen it drop to 25fps in massive fights with four players.

With lesser processors I've seen it hit the single digits.

the benchmark scene is useless and show no real fps drop under heavy situations. which is sad because of amazing settings and laptops variety

can i play diablo 3 with an dell inspirion m5110 with a amd radeon 6640G2 graphic card?

can i play diablo 3 ? i have laptop fujitsu siemens esprimo mobile d9500

I play on my Intel i5 with HD integrated graphics. (4GB ram)  I run on the lowest res widescreen, with all settings on low/off, and extra FX off.  It isn't the best framerate (prob 40s), but it is definitely playable.  Great job to Blizzard devs who made this work on my laptop!  The art is so great, that once you are immersed in the game, the low quality settings don't even phase you.

1080 high with no AA would be more interesting
