ledhead900 10 Posted November 2, 2013 What I am asking is since ArmA3 boasts PhysX and I am ditching my Nvidia card for an R9 280X for use with mantle related goodness, how does this effect the gameplay in terms of PhsyX how much does ArmA rely on PhsyX in ArmA3 will it be noticeable? Is it worth the frame drop or increase? are there any major issues with ATI "Non Crossfire" cards playing ArmA3? Share this post Link to post Share on other sites
Fushko 59 Posted November 2, 2013 The game uses CPU PhysX, so it will work even with ATI cards. Share this post Link to post Share on other sites
ledhead900 10 Posted November 2, 2013 (edited) What............... I really do not like the sound of that! This game is intensive enough with so much Ai logic routine going on that the last thing I want is for my i7 to be choked up with PhsyX processing. Thanks for the insights I can rest easier.

RuecanOnRails 10 Posted November 3, 2013 What............... I really do not like the sound of that!

Even when using an Nvidia GPU, the physx is run on the CPU only. There are no physx calculations done on the GPU no matter what card or brand you have. To answer the thread question, there would be no effect. Also the 280X is a re-branded 7970, you can generally find a 7970 cheaper than a 280X. If you're planning to purchase one soon, I'd suggest a 7970 as it's the same card before stock on them runs out. The only new cards from AMD this time around are the 290 and 290X, the others are re-brands. Share this post Link to post Share on other sites
ledhead900 10 Posted November 3, 2013 Yes I am aware of what the 280X is it is a 7970GHZ edition but its not just a simple re-brand. They are using newer technology on the pcb for somethings I already have one though pity was DOA but I already have purchased it. I only paid $180 for it because I sold my 670 in the processes. Personally I hate the 290X I think it runs hot and it is too loud and I'm not going to be running full water loops, I am just going to hold onto that 280X until mid next year and get what ever duel gpu design they come up with for the high end 300X range or crossfire the 280X. I don't even understand why they have a 290X the 690 and the 7990 are around the same price range well the 7990 is and they are a two gpu core design which eats the 290X for lunch and dinner when it comes to gaming under 4k, yes the 290X performs with a bit less of an FPS gap when talking about 4k but even with a 290X you will still need two of them to run 4k display at a responsible FPS and maintain ultra settings. Personally 4K is too young give it another four years and I might be interested. I'm sorry I should have explained that I am not an average user I am a power user with 16-17 years of IT experience under my-belt. Previous post I was just stating disappoint at the fact that there is no method to disable phsyx in ArmA because I really don not want it running on my CPU the CPU is not quite ready for that yet.

Disable physx? Do you realize that it is an actual physics engine, like bullet and havok? You can't just disable a physics engine in a game. ArmA 3 doesn't even use any of the GPU accelerated PhysX features. For example, all Unreal Engine 3 games use PhysX as their physics engine by default, it's integrated in the engine.

ledhead900 10 Posted November 4, 2013 This has been told to me already, but the post your quoted was my response to hearing about how It cannot be run on dedicated hardware that is a real shame because I don't really like physics simulations run on the CPU.

PuFu 4600 Posted November 4, 2013 Physix simulations ALWAYS runs on cpu, not gpu. What runs on gpus when it comes to physix is apex (cloth and particle simulation). Getting your facts straight before making a fuss about is always a good thing Share this post Link to post Share on other sites
