Hello everyone today I installed my new video card HD7870 ghz amd edition but when I put the high settings does not work well. the game stutters. lag and I have the new drivers installed 4.2.12002 but in the settings screen tells me compatibility profile context 9.12.0.0
What can I do? or is my cpu (intel i3 530 3.3GHz or c) that does not go well? please help me
Sorry for my orrible english but im italian

If you maxed out all the settings in the advanced graphics settings menu, try selecting the high detail presets instead.

Are you sure you installed new graphics drivers correctly?

[socetti]

yes i have a new drivers 13.4 but is possible when is my cpu limited i3 530 2.9ghz?

[jlv]

The CPU is fine. Try turning off demo recording.

anything is not good I have tried everything with all the other games is fine (buttlefield3 tomb raider moto gp 2013 etc) but mx simulator is not working. I installed a program to see the use of the gpu and mx simulator is 0% how is this possible?

[jlv]

It might only work for software that uses Direct3D. It could also mean you're getting software rendering. If I were you I'd try installing the graphics driver from AMD's site. You could also try the driver cleaner that YZ links to in this topic.

I've reinstalled and updated the drivers but it does not work well ugualmente.in this time to reinstall mx simulator and see what happens

[socetti]

nothing to do! mx simulator with hd 7870 does not work.
if it was a problem of drivers would not work the other games.
instead of the other games work perfectly! please help me

is possible mx simulator in not conpatible whit a amd hd 7870 graphic card?
i test in race 40 bikes in high fps detail mode and i have 5 fps is impossible play at 5 fps

The AMD OpenGL drivers are slower than NVIDIA's drivers, but they should still be good enough. The card should easily be fast enough.

The AI really eats a lot of CPU, so 40 AI riders is not a good representation of how fast it will go online. How many FPS do you get when you pause it?

[socetti]

72 fps in paused

[jlv]

I'd expect your system to be at 125 FPS when it's paused. You might want to go into Catalyst Control Center and reset it to the defaults. It's also possible for missing motherboard chipset drivers to slow things down.

Also, with that system you want shaders on. "normal" or "high detail" should do it. It will be faster and look better that way.

I have already tried it with the default settings and I have tried all drivers.
but nothing changes nothing! it is as if the video card is not present
you're right with this card I should be able to play at high details safely.
I make an example Battlefield3 90 fps in ultra details
if it was a driver issue would not work even in bf3
then I think it's a compatibility issue with mx simulator
however short will replace the processor and motherboard and I hope it goes better

[jlv]

It's definitely using the video card. With software rendering you'd be down in the single digits, maybe not even 1 FPS.
