Mantle Feedback/Bugs

The only problem i have with Mantle is a big cpu spike every 10 minutes or so, other than that it works well. Not sure if theres a memory leak or not as i can't enable monitoring overlays. I've not noticed one, but thats not to say its not there. I just can't get over how smooth it is, its complete madness. Another thing when you alt tab, its instant, like it happens so quick its just weird. On DX11 there is a pause.
 
Like 14.1 on first installation 14.2 played flawlessly under Mantle renderer. Only when I went to next play after starting PC/origin does it become choppy under both D3D & Mantle. So back to 13.12's again. Finding it hard to understand why it will play on first driver installation but not after subsequent restarts of PC/origin.

Though I am running a 7990 card and maybe the R9 29** are to be supported first as I guess people buying Hawaii may have been tempted by mantle as a decision maker. Encouraging to see some people like shanks having no problems at all. It's so random. Hopefully someone'll figure out what Mantle does and doesnt like.

May have another go dropping the settings as above but why do that when I can play flawlessly under DX11 with all bells and whilstles turned on? I could drop settings under DX11 andget more performance.

Seems like GPUZ works ok with Mantle. And i have to say when i jumped in that hardcore server on Metro i saw u in i was shocked at how smooth it was running. I know it was only a 32 man server but man i was averaging around 100fps on all High settings with 2xMSAA and seeing fps in the 120's a lot too. Just the whole moving around seemed like a new experience.. thats how smooth it felt for me :D

Btw the alt-enter for full screen is something i was telling some friends on BF4. It seems so crazy that it switches over THAT fast! :)

Not getting any CPU spikes here mate. Going to get a recording later of probably one of the most demanding 64 player maps Oman :D
Hopefully before the storm, play this last night and my god... Smooth
 
I think im getting the memory leak shanks. Maybe its more prevalent at 1440P as im using more memory. Nonetheless im delighted with how mantle plays and feels. Will post some screenies soon with some comparisons vs dx. I've not tried experimenting with settings yet, just using full ultra.
 
Possibly doesn't help that Dice updated BF4 on the same day as the patch dropped. My BF4 crashes after about 10 minutes play now, and that's without changing drivers from 13.11 beta 9_2 (BF4 does warn they need updating, as it did prior to the last patch as well).
 
RE BF4 crashes - I deleted my user.cfg even though the crashes I was getting with the latest patch wasn't in any way related to the issues that normally fixes and it seems to have stopped those crashes (for now) on that machine but my laptop never had a user.cfg in the first place and is still crashing within 5 minutes of joining a server. (This is without mantle - BF4 is just a shoddy half arsed game programming wise :S).
 
Somebody mentioned that if you install 14.2 then play the game straight after it's fine (although I had the memory leak).

Rings true as it was fine yesterday today it's FUBAR.

Mantle is awesome for the few minutes it is working but it needs a lot of work.

I'm going to play some BF bad company 2....awesome game still.

That worked Matt. This has stopped the 'Battlefield 4 has stopped working' message when going fullscreen.

Doing some testing now, so far i've got the game on mostly high except mesh and effects on Ultra 4 x AA FOV 90 + HBAO...shanghai is pulling 110-160 fps.

I haven't run out of Vram with these settings.

Not bad for a 5 year old CPU and 2 year old 7970s :)
