WWE SmackDown vs. RAW 2008 [BLES00137]

Nope. A game is Playable if it's Playable, regardless of specs.

If you can't run it with your specs, you need to wait for further RPCS3 updates.

i understand, i really want this game could be playable with Mid End PC, and not with Super Ultra High End PC specs.

Waiting for more att of RPCS3.
