EVGA GTX 760 2GB
- Launch HW:R, choose to launch Homeworld Remastered
- Load a campaign mission (or multiplayer map)
- Once loaded, move the camera around, especially around the background light source
- Alt-tab to the desktop, then resume the game
- Repeat step 3
In step 3, theres a lot of lag present. Particularly around the light sources. Once I alt-tab and then resume the game, most, if not all of, the lag is gone.
Optimum performance should be in use when the level loads. An alt-tab should not be required.
