Pretty much all cheap laptops have a locked bios so that you can't change any settings that actually matter. If you haven't, take a look in the bios if there are options to change such settings, if you don't know how to get into bios, google it. Also, in arma 3 (and most other games) you're limited by the CPU, not the graphics capabilities.
Interesting. I thought it was a gpu issue given that when I bring my details down my fps increases. But I agree. But im confused because my cpu sticks to 2.8ghz when active gaming. Recommended cpu speed is 2.5 I think...
Is it still a cpu problem? My cpu is quad core with hyper threading I think.
I would think so, I do have experience with a similar laptop, and while it performed rather impressively in somewhat graphically intensive games, the fps dived once there was alot of physics to be done on the cpu, so I was assuming that was the case with arma 3, but yeah.. there's not much you can do about increasing the performance on the laptop, aside from checking the bios if it allows you to change ram speeds.
Well Well I've been using amd overdrive and im able ti mess with the voltages to permanently increase to speed of the cpu...but that would result in an increase in temo.
I heard amd cpu handle temots of up to 99c...but since the apu includes a gpu...im unsure of the safe temp for the 7640intergrated gpu...would it be the same as the apu or cpu? I think rule of thumb for amd cpu is 99c.
