BF3 performance on GTX660M

Seems everyone who told me people who have the GTX660M would not be able to run BF3 at high to ultra settings were wrong, look at this video: https://www.youtube.com/watch?v=4TjRa2zCr6c&feature=youtube_gdata_player

 

i guess it also depends on the map, some maps are larger thus more demanding than others, also he got aninsotropic filter on 2X, on my 675m, with that setting i hit 60 frames at times on same map

 

He also had AA on 2x which means if he turns that off, his performance will be alot better as AA is a big hit to the performance of these cards... My GT650M GDDR5 is overclocked past GTX660M levels and is at the level of a GTX 550 Ti (so I've been told by many people) and I can run Bad Company 2 @ ultra settings, no AA and get and average of 50-60 FPS on the biggest maps

 

if you tuen off aa no games are really demanding .

I have a 6990m and can run all games high/maxed without aa just fine

 

BF3 is one of those games that I want to play with 50+ fps. I do very poorly at around 30fps. Not sure who said BF3 can't be played at high though with 660m. It can no problem. I wouldn't play at Ultra though pretty much no visual improvement for significant loss of performance. Plus the csdeferred command improves framerates greatly too.

 

What does CSdeferred do?

 

In terms of image quality? Nothing. Supposedly it makes lighting faster when there are a lot of light sources but I haven't found any situation where it's faster than having it off.

 

??? Seriously? It was what let me play on my DV6z at 1080p low/medium at 35-40FPS. With it on FPS dropped below 30FPS. It helps. I forgot the exact command line but will post next time I try.

 

I know what you're talking about. It's worldrender.dxdeferredenable or something. I use it too.

 

I play on Ultra settings with only shadows and mesh quality turned to medium or low depending on map.
This is on a FirePro M8900 or HD 6970m as it's also known.

The correct code for that 5 to 10 FPS boost is worldrender.dxdeferredcspathenable 0

It must be typed exactly as above including the space before the zero.

 

There it is, thanks. Works great doesn't it?

 

I watched the video and was a bit suprised. I get 50fps with his settings so hes prob getting 20-35fps whih is still playable.

 

He's running fraps though

 

Hi guys. This is the only thread I found with Google. I'm not sure, but from what I've seen (videos, tests, etc.), the 660M should have no problem with BF3.
I have Lenovo IdeaPad Y580 with Core i5 (Ivy Bridge) and 8GB RAM. But I can't play BF3 even on lowest settings sometimes. It like 30-40 FPS in most of the time, never hits 60. It's unplayable. And this is with many games that should run fine on lowe/med settings. I have Lenovo Energy Manager set on Lenovo Dynamic Graphics when I play, and battery is charger... Drivers are latest.
Any ideas?

 

You're kidding me right? Any modern graphics card can "run" any game!

To play fluently you have to have around 60 FPS. I'm sick and tired of people who can supposedly "run" Battlefield 3 on Ultra with mainstream graphics cards from 3 years ago.

 

Your CPU is the issue. BF3 stutters sometimes and is severely bottlenecked by dual core CPU's. BF3 *needs* a quad core Intel to really play well. The 660m should be able to manage BF3 just fine with med/high settings (turn off AA and all the extra bloom crap). But your CPU will be the bottleneck.
