Help with Game Performance

[Shade_Koopa]

Laptop System Specs-

CPU: AMD Phenom (tm) 2 P650 Dual-Core Processor
GPU: AMD M880G with ATI Mobility Radeon HD 4250
OS: Windows 7
RAM: 4 GB

Yes, I know, very crappy laptop specs. But I figured since it meets the min. specs, it could run this game on low settings. I ran the game on low, v-sync off, using multi-threaded rendering, and resolution at 800x600. I am still getting low performance playing this game. I don't expect stellar graphics or anything, but I still seem to slow down with any heavy action.

Any tweaks to help increase this game performance?

Not with that hardware.

The mobile 4250 has ZERO dedicated memory and relies heavily on the processor for video processing. So you're bottle necked at both your ram and CPU.

With a faster quad core processor you might be able to play lesser demanding games using that chip, but not with a Dual-core. That processor is probably about as good as an Intel i3. Not even remotely meant to try and run games.

Heh, kinda figured. I mean, I thought I met the Min. system settings. Figured there be some way to lower the settings even more.

I did some more teaking with the Ini settings, turning off alot of stuff. Run a little better. Oh well. *shrugs* guess I'll just have to make do.

May it helps even more to increase your fps

I tried that link, still getting low performance when things get heavy on screen.

Which maps are we talking about?

[Shade_Koopa]

Just any map. I tend to slow down when lots of action is going on.

Ok, just curios not that we are talking about heavy maps like Aka, WW or Tinkerers :)

If you have changed any particle/gfx feature to false or lowered them then indeed your hardware seems not capable to deal with dd. I assume drivers and your system is up-to-date.

[Shade_Koopa]

Yep, they are up to date. But the graphics card is old. It has no special features. And I have already set things to low.

That and its implications tells you what you need to know, there are zero ways to get acceptable performance in that situation.

No dedicated memory -> sharing main RAM -> sharing inferior memory bus & RAM with the CPU which also needs a great deal of that capacity to run the game -> doubleshit situation.
It wouldnt matter if the cpu was a topshelf overclocked i7 and the gpu a nvidia Titan, the shared memory bottleneck is that severe and the cpu&gpu being fast will in no way increase the memory bandwith.

Besides my stationary PC i have a cheap laptop with the same problem, anything 3D (anything requiring texturing really) and the framerate goes to hell.
Yes it can 'run' DD, as in it wont crash or refuse to run, but toddlers can crawl faster than it 'runs'.
On my PC I could probably downclock the cpu and gpu to laptop levels and still get much better results, simply because on the PC the GPU has its own RAM.
