telemole Posted January 26, 2012 Report Posted January 26, 2012 Hi Folks,I installed xplane 10, tried it on the pc and discovered it was time for a new pc - so out i went to shop and buy and build and hammer and drill (ok... not that last bit) and I built this : i7 3400 quadcore cpu (shows 8 cores in process monitor)AMD Radeon 6950 1 gig (set up as a single eyefinity group across 3 monitors at 4000ish X 768)8 gig ram7200 rpm driveand sitting on the runway with average settings in a Cessna my frame rate is about 12FPS I really expected this thing to BLAZE - I turned off HDR and turned off antialiasing and a few other options I had really hoped to have turned on and STILL only got it up to about 20FPS...I run iRacing on this new pC at 130 FPS with FULL detail, everything on... shadows, specular etc... on my triple screen setup - so i know it's capable of great performance... is there something critical I am missing in configuring x-plane?thanks in advance for any ideas - I'd love to watch this thing just sing running x-plane this weekend.Cheers,Telemole Quote
telemole Posted January 26, 2012 Author Report Posted January 26, 2012 this is actually the CPU - apologies : Intel® Core i7-2600 CPU 0 at 3411 MHz (x 8) Quote
Kesomir Posted January 26, 2012 Report Posted January 26, 2012 Turn everything to the lowest values and one by one move them up - that way you'll know where the bottlenecks are with your system. Don't forget you are driving quite a large display off of that, some things will have to be compromised on. Quote
Gjalp Posted January 26, 2012 Report Posted January 26, 2012 are you running HDR and Antialiasing at the same time? I have found that if you run one or the other, not both, your frames should increase and it should look better as well. I have just HDR on and it looks far better than AA.I agree with Kesomir though....turn everything off and start adding from there.Just my thoughts,AndyNZCH Quote
telemole Posted January 27, 2012 Author Report Posted January 27, 2012 Thanks to you both! The testing will commence tonight! I hate the reload times.. but I want to get to the best performance/balance becuase it's just so amazing to fly with a smooth rate, finally worked out my control issues, so i'm really appreciating it!

Kaphias Posted January 27, 2012 Report Posted January 27, 2012 Graphics card probably isn't enough to run a three screen setup, try it with just one screen and see what that does. Quote
karingka Posted January 28, 2012 Report Posted January 28, 2012 That's the problem I reckon. Three screens will destroy the frames. Quote
Cameron Posted January 28, 2012 Report Posted January 28, 2012 The issue is definitely the three monitors vs. that card. You are battling fill-rate.There really isn't a card to date that can handle what you're trying to achieve as a single GPU in games as heavy as X-Plane. SLI and X-Fire is it, and as of now XP still cannot take full advantage of this.The card that comes anywhere close to capability right now as a single GPU is the 7970. Quote
ARTIK Posted January 29, 2012 Report Posted January 29, 2012 Bad news 7970 is a screamer in every application/game except XP10, that's the very sad truth... My friend with i7 3+ GHz just upgraded his older ATI4970 series GPU for the fastest AMD7970.His 7970 XP10 framerate performance is worse than before... regardsarti Quote

I have seen reverse of what you speak of on someone else's machine. Nothing CRAZY, but a big improvement over the last series. Quote
ARTIK Posted January 29, 2012 Report Posted January 29, 2012 Yeah it's odd, XP10 behaves very odd&slow on ATI/AMD GPU hardware. LR says AMD "driver bug" cuts the performance in half ?!? Interesting. Every other app is happy with the 7970 but not XP10...arti Quote
larjeet Posted January 30, 2012 Report Posted January 30, 2012 (edited) I am getting 30+ FPS with the following system AMD Phenom II X6 1090T 3.2GHz 16 gigs DDR3 ram XFX HD6790 Graphics Card with the settings attached and no clouds but performance drops alot when I kick in clouds . You state that your friend was running a 4970 card but this card does not seem to exist are you sure that you did not mean the 4870? what driver is he using if its is still 11.12 get him to update to 12.1 driver as the 11.12 driver had very poor performance Edited January 30, 2012 by larjeet Quote
telemole Posted January 30, 2012 Author Report Posted January 30, 2012 CLOUDS!I turned down some detail quite a bit... left clouds on... the best i could achieve across my 3 screen setup (one eyefinity display of 3800 X 720) was about 20 FPS if i was lucky...turned off the clouds - jumped to 40-45 FPS... Why can so many other more intense 3d applications manage this and XP10 can't? I just don't understand... there is not that much complexity to the scenery and not that many polygons to render here... there MUST be a more efficient method... I'm sadly now curious to see how FLIGHT from MS is going to behave. My brother is in the beta and I'm getting a look this weekend... Quote
larjeet Posted January 30, 2012 Report Posted January 30, 2012 (edited) Clouds have always been a performance killer Not only with Xplane but FS9 and FSX etc also . I think when you look at games most of them are just being played in local maps . but with flight simulators you are continuously flying into a continuosly changing horizon based on reality . This is why if you fly out over the Ocean or climb into a blue sky your frame rates increase as your GPU is only dealingwith a few textures . but throw in thousands of constantly changing Puff balls AKA clouds and autogen buildings, trees , ground textures that are constantly changeing in size you will realize that a flight simulator is probably one of the most intense application out there.

ARTIK Posted January 30, 2012 Report Posted January 30, 2012 Try fantastic Cloud Maxx beta and report speed up:) Turn down cloud detail to few%http://maxx-xp.hiking-pa.com/?page_id=147regardsarti Quote
