GTA5 on Radeon R5 M335 4GB??

I hope it's ok to post this here. My question is about a laptop and I didn't buy it from OCuk.

Just got a new laptop and it's really struggling to run gta5. I've got all the settings turned down to low, anti aliasing off, anisotropic filtering off. It's down at the most rubbish settings pretty much, but I do have the screen res at native (1920 x 1080).

The most I can get from it is about 17 - 20 fps. I've even used the amd software to OC the graphics card, but didn't see much difference.

It has the following specs'.

AMD Radeon R5 M335 4GB DDR3
6th Generation Intel Core i7-6500U Processor (4MB Cache, up to 3.10 GHz)
8GB Dual Channel DDR3L 1600MHz

I hope someone can advise. I thought I would at least get a playable 30fps on this machine.

It's a weak GPU - not much more powerful than integrated really. Best bet is probably to lower render resolution to something like 1280x720.

Ok thanks. I should have done more research before buying the thing.

I can run it at 1366*768 at mediumy settings on an Nvidia 650m at 30+fps, I'm not sure how different these cards are but probably not a million miles apart? Could it be low clocks on the u variant of the i7? With all 8 threads going on it might only hit 2.6GHz or something...

I don't know the answer to that to be honest..

Performance is so bad that I was convinced that the game was usiing the intel graphics, but last night I ran the game with gpuz running, and I could see that it is the amd card that's working when the game is running.

Even Garrys Mod only gets about 25fps. I've got it on max settings but I've always found that you can max out Garrys Mod on almost any hardware and get good fps.

It's got a crippled memory bus and its performance is only just better than integrated.

I thought with 4gb of graphics memory it would be a half decent card. Assessing pc specs is annoyingly complicated.

Anyway to un-cripple the thing. I gather you are saying there is an imposed bottleneck?

Yeah it's got a lot of RAM but a 64bit memory bus which is about as slow as it gets. It's a marketing trick used to sell low end cards.

No way to get round it as it's a hardware limitation, you could over clock it a bit but gains will be limited.

Well the trick certainly fooled me

Thanks to everyone for your replies. At least I know what the problem is now.
