Blizzhackers

since release i've been suffering poor performance in D3 (and only D3) on my htpc.

main specs;
Q6600 (@3.0ghz)
4GB ram
AMD HD6850 (latest drivers)
game is installed onto an SSD (500mB read/write)
120/12 mbit internet connection (likely irrelevant)

It's well cooled, and maxes (bar AA in some cases) most games that i play (DiRT Showdown, Deus Ex:HR, BF:BC2, Max Payne 3) at 1080p/60+fps whilst recording.

afterburner tells me D3 is running at 120fps sometimes (which it obviously isn't by looking, it stutters obviously) and it drops to 28FPS if i am recording.

I only play in 1280x720 windowed with all settings on low (other than texture), vsync off, AA off, max FPS at 60 and it's just annoying me now.
I get random stutters around teleport/vortex elites and any large enemies and I'm get raped in inferno because of it.

My laptop (lower spec, some i3 processor, 4gb ram and dedicated amd card - unsure which) is maxing it fine at 1080p/50+fps (with vsync off).

Anybody else getting performance problems?

Yes, I am running a 4.5ghz overclocked I7 920, 6gb of tri channeled DDR3 ram, 2 GTX 295s (even tried SLI off and 1 card in).

I go from 200 FPS to 30-45 just from joining a multi-player game. If certain spells are used in a game with 3 or more players my FPS drops to almost nothing, odd considering with 2 people it's perfectly fine.

I also noticed my frame rate does not change with filter on or off same with V-sync, resolution or detail.


Apparently this has become common after 1.02b came out and is supposed to be getting addressed with 1.03 later today. We will see and I am hopeful.

In beta and pre1.02b I was getting a steady 90-200FPS. Too avoid screen tearing I locked my framerate at 60FPS and was getting a amazingly smooth picture but this patch killed it.

It's not just you.

Is something else hogging resources?

Go into msconfig (Start Menu -> Run), choose "Selective startup" and uncheck "Load startup items". Restart PC and try again, does anything improve?

Nothing else is using resources. It's a clean-ish Win7 install, all that is installed is D3, Max Payne 3, XBMC, and FileZilla at the moment. (all on an SSD). There are no startup items other than Catalyst Control Center.

I blame screwy hardware.

I don't... I'm maxing other games which should be more demanding (max payne 3, DiRT: Showdown, BF3 to an extent)
I blame blizzard

When it comes to AMD graphics cards, 90% of the time will be driver issues.

I have nearly an identical system except I use 6870 and have everything maxed out at 1920x1080. Try older drivers.

I'm using ver.8.8

8.8?

their drivers are named YEAR.month

im on 12.4

It says on properties

Driver Date: 28/07/2011
Driver Version: 8.8xxx.x

oh right, well that's confusing as hell for me now

On the site they're all named by year.month
