post #2111 of 2769
I don't believe they are, I switched to Mantle last night (2x R9 270x) after the update and HORRIBLE FRAME DROPS AGAIN. I'm on 14.3, doesn't matter if it's 14.2 or .3, same performance issues. Guess we are still waiting. I had high hopes when I saw the updates to Xfire etc, alas, no go.

Yeah I've tried all the betas too, and have the same results as you with the frame drops. Granted I'm only on a single 7970. I will say though that the 13.12 driver and BF4 get along very nicely. After the patch from yesterday the game is the smoothest it has been since its release.

It is supported, just not optimized

it wouldnt run at all on the mantle render path if it wasnt supported.

Haven't there been people with 280x's and 7970's getting decent performance with Mantle?

The performance is great with this 7870 XT until it hits ~1900mb vram and starts stuttering. All these memory management and leak fixes are only for Hawaii and Kaveri APU?

Hawaii has 4gigs, so running out of vram is less of an issue.

Just turndown the settings. Expecting to run ultra with 2 gigs is a bit unreasonable.
post #2116 of 2769
Never said anything about ultra. Turning down settings doesn't make a difference. Even on all medium no AA it still works its way past 2gb.

So I had to drop to 1 card for now but at least Mantle is working. in BF4 I play on high and lightningon medium 2560x1440 @ 96hz and have a frame limiter on 95Hz and must say fps never dips below 95FPS. This is awesome and it can only get better on the next drivers. I played bf4 last night for about 2-3Hr and not a single stutter or anything like that

Hehe I actually did update my rig and then saw your post, funny timing! I'm not on here a whole lot so never really thought about it before, but it definitely will help if people are troubleshooting. And yes, they are supported but not optimized, I have seen very few if any posts from people with 7xxx series that have had any decent results. I've tried three different cards, 3 drivers and 2 OS'es and had the same results everytime, this includes different revs of the game.

I will say moving from Win 7 to 8.1 Pro increased my frames by a good 20+ and completely eliminated frame drops. With crossfire R9 270X's I have only dropped below 60 (frame limited) once or twice on Shanghai, 64 player map looking from E towards the skyscraper. Beyond that, it is soooo smooth, and the new maps are excellent, I think they run better than any of the previous maps; they really have a winner with naval strike.

that does seem unreasonable.

Lots of people with 7950/7970 have been having great results, so its only a matter of time.

Hey Mac,

I'm curious about my Firestrike results, I scored 9444, what are you getting with the R9 290? I've looked up results online but it's always nice to be able to compare scores out there with real results. I kind of want to see how crossfire 270's look against a solo top of the line card.
