Intel 4500mhd Shared Video Change Allocated Memory

intelMy mostly spiffy new Acer 1810t laptop uses the Intel 4500 video chipset. It’s fine for video as long as you’re not a modern gamer. If you like playing older games, it works fine. However, unlike older integrated video processors, there’s no easy way to directly change the amount of shared memory allocated to video. The Intel 4500hmd uses new fangled Dynamic Video Memory Technology (dvmt) to control memory on the fly. Problem is, it doesn’t work well.

Intel 4500mhd memory allocation problem

There are plenty of gamers complaining, “the 4500mhd won’t allocate the maximum memory for my game!” But usually, more memory won’t help them. The Intel 4500mhd isn’t meant for modern gaming. Poke around on Google for threads re: what games can be played.

Some people have suggested changing the settings under: Intel Graphics Media Accelerator Driver for mobile -> 3D Settings -> Driver Memory Footprint – but everything I’ve read has been telling people to set it to “high” whereas the Intel site indicates that setting the driver memory footprint to high will unconditionally limit the amount of memory, maximum allowed texture size, depth buffer precision and amount of textures kept in memory. FAIL.

No wonder everybody trying “high” hasn’t noticed any improvement. To be fair, Intel really dropped the ball here. Yes = No ?! High = Low ?!

My problem is exactly the opposite of the 4500mhd RAM gaming conundrum partially solved above. I don’t use my rig for gaming, and I want to be able to use as much of my four gigs of RAM for things like Photoshop swap files and whatnot. So… I’m going to set Driver Memory Footprint to “High” – restart – and hopefully I’ll notice more than 3 of my 4 GB RAM available to me.

More from the Intel site:

Normal (Default Value) – Driver automatically determines memory based on available memory.

LOW – Driver does not reduce memory footprint.
