Boost in FPS within WoW may indicate a PC upgrade opportunity.
Boost in FPS within WoW may indicate a PC upgrade opportunity.
You've got a solid setup with a 1440p display, a GTX 1070, and plenty of RAM. The performance hiccups during intense moments like raids and battles are common. An i7 could definitely help smooth things out, especially for smoother frame rates and better stability.
Open Rivatuner, review CPU, RAM, GPU, pagefile and disk stats. Identify the component needing attention and upgrade or fix it.
Your GTX 1060 runs at ultra wide 1080p with stable performance, never dropping below 50 frames. You might want to verify if V-Sync is turned off in other games, as disabling it can help prevent random frame caps and lower performance due to the card misinterpreting gaming load.
WoW consumes a lot of CPU power during raids, and I wouldn't suggest upgrading unless you're targeting Coffee Lake. If you decide to upgrade, higher clock speeds will likely provide better results than adding more threads. Right now, the best approach is to enable Windows power management at its highest setting. By default, it uses a balanced plan that limits full-speed performance during long sessions. You might also consider a slight overclock, and reducing UI elements can help too—something I've tried in similar games.
