Massive GPU frame time spike on Syria map (VR)

I have an area on the Syria map where my GPU frametime jumps from about 9ms to 40. In this area I have positioned 3 mortars, constantly bombarding a point a thousand odd feet ahead of them. I'm assuming this is what's causing the spike but why? recommendations to solve it? I also have a reaper drone in that area also so I guess it could be that. Haven't tried removing either yet.

Seems odd that the GPU spikes rather than the CPU

While I don't know anything about how this is done in DCS, many graphics engines take a big hit when they have to process lots of transparencies and particles. Transparency is used for smoke and flames, particles for fire, explosions, shells etc. So it would make sense that if there is a lot of bombardment, I hazard a guess there are lots of particles and smoke. This may be a factor.

To find out if this really is contributing to this, remove the bombardment and see if that helps.
