Summary0005596: r_lockSurfaces broken
DescriptionI wonder if it used to work and when it got broken
It should be a useful tool when examining large areas performance problems
Steps To ReproduceBlackgrove Manor spawn location, looking at the mansion
invoke r_lockSurfaces 1

Expected: more or less regular render with ability to move camera
Observed: camera frozen, flickering
Additional InformationThe first obvious thing to fix is lockSurfacesCmd->viewDef, which will clear and reset next frame in idRenderWorldLocal::RenderScene by a R_ClearedFrameAlloc
I tried copying that to a static var, but then got backEnd.vLight->lightShader == null in the backend
TagsNo tags attached.

So they don't switch SMP frames at all, huh

 Yes, no SMP yet.

Though Daniel appears to be ready to accept a patch request from another Doom 3 multi-threaded project so that might change in the near term.

I just brought the details here in case any of the changes might assist with your work.

 New Job - here it still seems to work with SMP and scissors off
Might have something to do with draw call count

Animated Grass Demo has AI faces that stretch for several meters when you enable this ( pretty trippy )

Moving to 2.11 unless any further fixes are concidered

This appears to work now except portalsky is black. That can probably be fixed using the same fix used for g_stopTime and portalsky
