MSI twin fzr 7950 1000/1400 low fps in bf3?

[4737Joker]

Hi,

I got my new gfx card on monday, installed it etc. overclocked it to 1000/1400.

Launched BF3, cranked it up to ultra. Fps when stood about was about 70 ish (in a room,not in the open) when in combat it dropped off to about 30.

I was kind of expecting it to be around 60 based on anandtech, is 30 a low fps to be getting from a 7950 in bf3?

Do you think my cpu is a bottleneck and could be causing this or is it just me expecting too much out of it

I say for sure it is a CPU bottleneck. Monitor your CPU in game and if it is hitting 75% it will start to impact on your GPU performance.

It was 95% when i had my 6850, ill check the cpu usage tonight.

based on previous threads and other things i have read i assume the below would be a good upgrade path to take;

YOUR BASKET
1 x Intel Core i5-3570K 3.40GHz (Ivybridge) Socket LGA1155 Processor (77W) - Retail £184.99
1 x Gigabyte Z77-D3H Intel Z77 (Socket 1155) DDR3 Motherboard £81.98
Total : £278.38 (includes shipping : £9.50).

Good choice. I am not sure if you will need to flash the BIOS for that mobo and Stulid will confirm if you do.

Whatever way, good choice and simple to flash a BIOS.

A 2 core CPU and a top end card like the 7950 is not a good combination.

Looks like a CPU bottleneck. BF3 64 MP is actually deceptively CPU intensive.

Yes, it is.

100% a CPU bottleneck

The 3570k will be a very nice upgrade

With a Z77 board i'd be surprised if you needed to update your bios for an Ivy chip. Z68 is a different matter.

 

[chris74]

no you do not need to flash that z77 board.

Was there not an issue with that motherboard and certain GFX cards, maybe even certain brands i.e. MSI ? That required a bios update.

As said Stulid will know.

wish id have bought the cpu when it was on offer now. At least the board is at the moment.

I don't mind flashing the bios if i have to, as long as i can get the most out of my gfx card

You will And you'll benefit elsewhere besides just games too

Just tested the cpu usage, mostly at 83-86% dipping in to the 90's on occasion.
