Alright guys, because I think it is important to note in here - I have some performance and observasion numbers from Diablo III.
No, I don't have them on the Nvidia Quadro 1000M either.
First, the machine, and settings.
I am testing on Windows 7 Home Premium (fresh install) with the Lenovo W520. This includes the Intel 2620m i7 processor with 2 cores and HT. This machine has a recent upgrade to 8GB patriot 1333mhz ram running in dual channel. I tested today with the Intel HD3000 GPU. Intel Driver version 184.108.40.2068. My display is, of course, the 1080P display for this model and running at 60Hz (yes there are other options for this display). The Intel drivers are set on maximum performance (no battery savings here!
) and Balanced quality.
In game, I tested at 2 common resolutions, and found the best playable settings. I also determined what did and did NOT have any effect on frame rates. All frame rates were taken as the average displayed on FRAPS. I tested in Act 2, by playing in the desert. The Post FX limiter was left OFF during all testing. One last important note: Diablo III is only sensitive to frame-rate issues UNDER 20FPS. 22fps (average) worked out to be perfectly playable, though showing an occasional rough spot. At no point, was any of the below results unplayable unless specifically mentioned. Of course, your mileage may vary.
Ok, here goes:
At 1366x768 I found that with ALL settings on, except for AA, I could run with shadow settings on medium, all others on high, and maintain a 22fps average. At no point during my game (thus far) did I find it unplayable, or distract from the game play. Know that on high resolution displays though, this is anything but ideal. If possible run at your native resolution. Note for Mac Book Air, or similar ultra-book owners, this is what I found to be the best balance of playability and game quality. If you are on an HD 3000 with a 720P display, use these settings, and you will have a perfectly pleasant gaming experience!
At 1366x768 WITH AA turned on, I could keep all settings turned up, except for shadows. I had to disable shadows entirely. On this setting, I was seeing 34fps average.
At 1366x768 without AA and NO shadows, I was averaging 36fps. Note, than when I turned off ALL other settings, or lowered them to minimum, I saw a mere 2fps change. Not worth it considering the amount of quality you lose.
At 1920x1080P, I only found one playable setting: AA off, Textures high, Physics high, ground clutter high, shadow OFF. This netted me 22fps outdoors, and 24fps in caves. For those wanting to know, YES the HD 3000 CAN play Diablo 3 at 1080P, and still be perfectly viable.
Obviously - you DO want to have dual channel ram, as your memory is shared you need all the bandwidth you can get. Also, you should take note that I am using the i7 chip - which may work out to be considerably faster than the i3 or i5 SB cpu's. I do NOT have any idea what will happen in those situations. However, I can tell you that if you find that the CPU is the limiting factor, reducing the Physics effects setting will reduce your CPU load. As will the lower FX setting. Use them if you run into CPU limitations.
"There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'"
