Will increasing the amount of dedicated VRAM better gaming performance?

I bought Bioshock Infinite this week to play on my notebook. But first I want to make it clear: I wasn't expecting when I bought the game to run on High settings, since I don't have a high-end notebook. And it ran preety well on low settings, so it was worth the risk of buying the game. But I was curious if I could better the performance. So today I searched a little on the internet about Increasing the amount of dedicated Vram, and found out I can actually do it on the BIOS (F2 on startup). My question is: Will taking dedicated Vram from the shared Vram really increase the gaming performance?

Specs: - Intel HD Graphics 3000
(64MB of Dedicated Vram and 1696 of shared Vram)

- Intel Core i3 2310M CPU (2.10Ghz 4 Cores)

- 4GB RAM

-Windows 7 Home Basic 64 Bits

True true. You get looooot more bang for buck. And you can transport PC too (bodybuilder needed). But I think that he cant get another computer.

Back to the topic.
When you run out of run your Vram your FPS will fall down as a crashing plane. If you got too much itll go up for, yes Im not joking, for whole % (maybe 2).

Thanks for your answer, will try that out. Other than that can I do anything?



I'm saving to buy this year a decent gaming desktop, thanks for the advice anyway...

Edit: grammar error

So you're saying increasing my dedicated Vram will make my FPS stop falling to 10-15 frames because it won't run out of Vram anymore?

Edit: a missing word

Sometimes yes. But sometimes your (i)GPU is the problem. If there would be 1000$ GPU with 1kb of Vram Its going to be 20 fps on some lame game. And there could be 50$ GPU with over 9000Tb of ram and there will still be 20fps. There needs to be balance.

Your Graphics can be choppy no matter what you do (somethimes incrasing settings helps for some reason) but in some cases incrasing Vram helps.

I get it, but is there any risk of doing this?

Usually not (99,99%). But Im sure that you can do something wrong if you try (kick CPU till it gets more Vram (your GPU is in your CPU), throw it off random building...). Oh and dont give whole ram to graphics.
Good luck!
 
Because the igpu uses ram as its vram, there is no performance difference in setting it higher unless your ram is being filled. The igpu will use as much shared as it needs so having it dedicated or not makes no difference in how much it uses. You can test it yourself and see if it affects it, there is no risk. Set it to the lowest, see your fps then set it to the highest and see your fps.
 
Your problem is NOT the amount of VRam + shared ram, it's the HD3000 that is limiting your FPS.
Here is a example of HD3000 using a quad core SB CPU, you have a lower level SB CPU therefore your scores will be lower.

BioShock Infinite(2013)
low: 22.8 23.3 ~ 23 fps
med.: 10.6 10.7 ~ 11 fps
high: 9.2 9.3 ~ 9 fps
The benchmarks indicate that the game is not playable in the tested settings

Ref: http://www.notebookcheck.net/Intel-HD-Graphics-3000.37948.0.html
Scoot to the bottom left and you can get a idea of FPS for various games, just remember that the scores are based on a Intel quad core and you have a lower end CPU so scores will be lower.

PS I also have a laptop with the HD3000 (an i5-2410M) - great for playing card games, watching DVDs, but not so hot for gaming -LOL.
