Greg likes to Quote Nvidia's DX12 PR so i'm just wondering if that quote makes him think Nvidia are in some sort of privileged position or in someway have more involvement than anyone else.

Truthfully, I have completely no idea and just read articles on tech, so that is all I can go on. So long as it works for me, I will be happy.
You seem to be on a mission today for making me out to be an nVidia fanboy...No need, as I have said many times that I am
But no nVidia or Intel support, or older AMD hardware. So really not that attractive then. OpeGL already gives Linux, OSX, and older windows support for Nvidia, Intel and AMD hardware.
This is actually funny as I asked my friend couple of years ago why they don't make games for Linux with OGL, and only answer I got was laughter. I don't pretend to understand anything about the difference between dx and ogl, but certainly there must be a reason why devs don't like to use it.
Looks to me you probably think AMD invented Mantle.
Devs don't see the point in making Linux games full stop, it has nothing to do with OGL. OGL is a great API and a widely used cross-platform standard used extensively in industry and commercial graphics applications.

Let's say that nvidia and Intel adopt mantle as an api and support it and such, will nvidia cards be able to run current mantle games like BF4 and, um, y'know other mantle games? (it's 2am and I have had a few.. )
I do, am I wrong?

As it currently stands, bf4 doesnt run that well on mantle or DX. But thats probably more down to dice's incompetence, probably pressured by ea to fire out a game that wasnt ready. It took over a year to get bf3 to run ok, but still not as good as the so called console game bfbc2. Imo the best bf game in reent years.

BF4 actually runs superbly on Mantle, for me at least, but there are people who complain of Memory leaks, usually on 2GB cards, sometimes 3GB.
I think that may be a combination of Memory leaks on older gen cards and / or simply not enough Memory.
My 2GB Tahiti LE did have a memory leak at the time i had it, i found a fix for it, but i know it can be a problem with BF4.
But with the 290, Mantle on BF4 is fantastic
awesome performance and so smooth its unreal. feels like a big fluffy duvet on a silk clad mattress.

Tbh mate, bf4 doesnt totally max out vram on 2gb cards at 1200/1080p. Which id suspect is still the res of most users. I see 1900mb max at 1920x1200 on the highest settings with sli 780's. Previous to those cards i ran 2gb sli 670's, but lately nvidia drivers have been poor for bf4 with sli, normally my minimum fps is in the high 80's, but im seeing drops into the 50's. Not great on a pair of cards that can normally blitz this game. Yes sometimes the sever you play on and lag with it can make a lot of difference. As ive mentioned before, my very limited use of mantle was on a relatives system, a 290 with a 3570k at 4.5ghz, which i clocked for him as it's a cpu i know well from having one myself. Mantle fps minimums were higher than my own setup in sig with one 780, but both felt good. Iirc Rusty has mentioned the same as he has owned both cards. Im actually considering a 290 for my second rig, an i7 930 @4.0ghz.BF4 actually runs superbly on Mantle, for me at least, but there are people who complain of Memory leaks, usually on 2GB cards, sometimes 3GB.

Yeah, it didn't max out the VRam on the Tahiti LE, at least not in DX, In Mantle it started fine, but the VRam soon climbed and climbed.... until it was full, then the stutter started.... Defiantly a leak.
Turning Texture Quality down to medium cured it.
I don't know if thats been fixed since or to what extent, i have not had the Tahiti LE card for about 8 Months, but there still appears to be a problem from reading around.
PS: i had an i7 930, good CPU. very much able to hold its own despite its age.

Ive got a 930 myself mate, clocked at 4ghz, (it will do 4.3ghz stable) but its a very poor board for windforce cards in sli. I darent stick my 780's in it as the top one would hit 100c+ in seconds, (very tight spacing) which i found out with wf 460's in sli. The spec in sig runs bf4 very well, but the top card does get a bit hot. Hence i might try to pickup a maximus 6 extreme, but knowing me then ill be tempted to bung in another 780 for some tri sli action. But the formula board looks good in my current setup, yes im a wee bit pedantic about how my system looks.

Probably worth mentioning that Mantle performance characteristics in games are the purview of the developer, not the driver, but we’re continuing to collaborate on performance optimisations.
That said the developer is working on a patch to fix these issues. I suspect your cards may be running low on vram as pcgameshardware have tested the patch and report significantly lower vram usage.

Never had problems with mantle in bf 4 either, runs SUPER smooth in comparison to DX, perhaps it is because I run everything on low/off except for mesh???

Running on low will help on both mantle/dx, iirc you have a 290 Nexus, id be interested in seeing your figures at 1080p with both mantle and dx, max settings as I'm sure a 290 could handle it fine. 780 can which is similar to the 290.
I also did a single player run on max settings a while ago:
max settings except no AA (IIRC I had 150% res. scale though) at 2560x1080 on my rig as specced in sig, single player:
That minimum FPS figure for mantle is wrong though, I never seen the FPS hit that low during that run, not sure why it reports the wrong minimum FPS figure 
But yeah as you can see, DX isn't playable at all on my 290 and i5 750 with max settings.

Interesting, so you reckon mantle is just more vram hungry so at 1440p it's dealing with memory shortages? That would explain the stuttery performance. Afterburner reports 5.8GB used (across both cards) so I didn't think that was the problem though.

Possibly Dev, not entirely sure just going on their findings. Hopefully will get chance to test it myself soon.
