If the question you are asking is "I have graphics lag when explosions occur on screen, how do I fix it?", then the answer is to reduce the detail levels or upgrade your hardware. Despite all appearances explosions are extremely graphically complex, full of overdraw and more geometry than a high school textbook, so they're going to cause an FPS hit.
I do not use high settings all on high shows that I have 1GB of free memory in all the other games I work a great card games like GTA V unity but did not run it well
GTA V does not run 100% smooth on CrossFire. I have tested this on my personal system. To get smoother performance i recommend using Vsync and setting FRTC to 1 below your refresh rate.
GTA V runs lovely on my 380 crossfire setup, butter smooth. If only i could get this 3rd card working.
I also tried to put out the msaa and the fxaa I also tried to change the meduim not help it move blasts of such annoying
Only in this game it happens to me
I tried did not work ,
Do not understand why the game is not running smoothly , I have an i5 processor 4460
And a video card R9 280x sapphire
8 gb ram
So that should not be a problem running the game
