Sapphire 7850 Performance Thread

actually, if you look at the graphics score it went up. The ever so small OC did improve the graphics power.

Physics score however, will always be in the hole for you. It is a AMD system which does not handle physics well as is.

I think that's why GW2 struggles. It's got a lot of physics stuff going on.
 
Chances are then that it would run better on an intel system (as I understand it Physics is aided a bunch for higher IPC processors). Even a Nvidia card would help a bunch with physics.
 
The reason your PhysX is so low is because your running a AMD video card. It forces all the PhysX to be run on the CPU. PhysX score will suck if forced to run only on the CPU with Intel or AMD. Your PhysX score will really jump up if you had a comparable Nvidia card as your 7850 with PhysX running on the Nvidia card.
 
Of course isn't all the PhysX stuff just really good drivers for handling physics? wonder how good amd gpus would be with equally good drivers
 
Physx is a Nvidia tech jonny. It is not drivers, they own the rights to it. Assuming that they could do the same thing, it would not perform as well because they are new to it. If they had teh same amount of time at it as Nvidia, then they would probably do just as well.
 
I filed a nicely worded question to the support team of Guild Wars 2 to see what they had to say on the matter.

As follows.


I've got the following specs on my system that are relevant to my question.

Phenom II 955 Overclocked to 3.4 gHZ
Sapphire 7850 Overclocked to 1000mHZ Core and 1300 mHZ Memory
4GB DDR3 1600 RAM
Seagate 72000 RPM 1TB HDD
MSI 970A G45 Motherboard
Corsair 600 Watt PSU
1600 x 900 resolution

Now my computer clearly meets the recommended requirements and should easily run the game at full settings but I can run medium settings at best. I recently upgraded my video card from a 5770 to a 7850 and saw maybe 10 fps increase overall while my other games almost doubled in performance. I know the game is fairly new and performance is being ironed out but I'm still slightly incredulous as to why I'm getting such poor performance.

If it's relevant, when my Processor and Graphics card were at stock clocks, the performance was lower, so Overclocking did help a little but not a whole lot.

Drivers are all up to date and my computer is in perfect working order. Just Guild Wars 2 does not run as well as it should.

A friend said something about the Physics engine being what bogs me down as AMD isn't the best at doing physics based calculations in comparison to Intel. Still, not sure what it is.

If you can offer any insight on how to go about fixing this or if anything is being done about AMD optimization that would be greatly appreciated. Thanks for taking the time to help me.

Game is awesome by the way. :)

Edit: After reading a couple settings they recommend changing for AMD cards my performance skyrocketed. Not sure why.

Settings as follows that I changed.


For AMD cards:

1. Right-click on your desktop and select "Catalyst Control Center."
2. Select "Preferences" and left-click "Advanced mode."
3. Click the "Gaming" tab on left.
4. Select "3D Application Settings."
5. Under the heading "Anti-Aliasing" checkmark "Use application settings" but do not check "Morphological filtering."
6. Under the heading "Anisotropic filter" checkmark "Use application settings."
7. Under the heading "Tessellation" checkmark "AMD Optimized."
8. Under the heading "Catalyst A.I." move the slider to "Performance."
9. Under the heading "Wait for vertical sync" move the slider to "On, unless application specifies."
10. Under the heading "Anti-Aliasing Mode" move the slider to "Performance."
11. Click "Apply" to save these changes.
12. Start Guild Wars 2.

Once loaded, access the "Graphic Options" window and make the following changes:

1. Change "Refresh Rate" to "60 Hz"
2. Change "Frame Limiter" to "60."
3. Change "Reflections" to "None."
4. Change "Render Sampling" to "Native."
5. Enable "Vertical Sync" at the bottom.


Not sure why that changes anything. I turned up the reflections back to sky because it looks horrible otherwise and performance didn't change, however turning in to all totally crippled my system. After doing these changes I selected auto detect settings and it bumped everything up to high, while before those changed it gave me a mix of medium and a little bit of high. So basically V Sync and locking my framerate at 60 helps. A lot of the CCC changes were already the way they were supposed to bed.

WHY YOU NO MAKE SENSE?!?!


EDIT EDIT: GW2 video added to OP.

not to say it is true, But I agree with jason there. If it makes sense, chances are you are doing it wrong in computers.
