Hi guys im new here my first thread

The problem with my pc is that when i am using crossfire which is my sapphire 7970 and my gigabyte R9280x (which both work fine and r compatible with each other and work well for my other games such as crysis 2 3, alan wake american nightmare, battlefield 3 4, team fortress 2, left 4 dead 2 and starcraft 2 wings of liberty. AND YES I HAVE THE LASTEST DRIVER AMD CCC 14.4) in Alan Wake when the "Taken" arrive i would start seeing the screen flicker and in starcraft 2 heart of the swarm in some maps like char i would see the terrain flicker but i have no problems with the maps in wings of liberty. what stops the flickering is that when i disable the crossfire but i want my game to run smooth with crossfire. this happened when i first started crossfire


the clock settings for both cards is GPU 1075mhz and memory 1500mhz
CPU: i7 3770k 4.4ghz
RAM: 32gb
monitor refresh rate: 60hz
OS: Windows 7
PSU: 850w

wut do u think the problem is? did amd screw up on their fixed updates? is there a setting or method i can do to stop it?

methods i tried and didnt work
turned on and off vsync
changes cpu & gpu clock settings
virus scan
reinstalling CCC
disk error check

please help and thanks

awww well i guess the only other option is to hope that amd with notice the problem and perhaps fix it...
but what is strange is that starcraft wings of liberty has no problem with crossfire and yet heart of the swarm does...

problem solved for Alan Wake
sorry for the late reply
in CCC for the settings for anti aliasing i set it to use application settings and for the settings before was edge detect now put on standard
for alan wake when the taken arrives i see the no flickering or a bit of it but not as often
starcraft 2 Heart of the Swarm is still a problem....

I know its been a while but i recently found out my Starcraft 2 crossfire flickering terrain problem!

So to fix the flickering on some maps,
set stacraft 2 in full screen mode to enable crossfire,
set you favorites options, exit the game.

Now browse into C:\Users\yourname\Documents\StarCraft II\
Where C is your windows drive letter and your windows login/user name,
replace those two.

open the Variables.txt
it contains starctaft 2 settings.
search for the word TerrainTextureSize
replace the current number that is next to it with the value 1080

example:
TerrainTextureSize=768
becomes
TerrainTextureSize=1080

Enjoy stacraft 2 in crossfire mode !!


Alan Wake still yet to be solved cause i still see a bit...
