this is mostly undoing e50a60fe17
and warning when delayed loads happen in quick succession
with this change:
- we no longer block legit looping sounds like the RG hum
- we only warn when there are too many loads instead of spamming for legit stuff
surfaces added first are part of the map itself
it's better to drop e.g. some plasma cells rather than e.g. entire walls
it's also less error-prone to work with since we don't need to fix numbers on read
but only check on write in exactly 2 spots
also removed tr.shiftedEntityNum because it was unnecessary...
after getting DXGI_ERROR_DEVICE_REMOVED or D3DDDIERR_DEVICEREMOVED,
GetDeviceRemovedReason can return DXGI_ERROR_DEVICE_RESET
this particular case should trigger a video restart instead of a fatal error
- r_alphaToCoverageMipBoost scales the alpha value based on the current texture LoD
this prevents the "fading with distance" effect
- mip 0 dimensions are tested to decide whether contrast boosting around 0.5 is enabled
this is to deal with high r_picmip configs
- improved algorithm for excellent sharpness and minimized temporal artefacts
- GLSL 4.00 is required for the GL3 backend to use A2C (for textureQueryLod)
the issues were:
- screenshots were black because of mismatched dimensions in the CopyResource call
- display was showing garbage because the scissor rect was too large
also increased the buffer's size (e.g. to draw all chars in the console in 4K)
one of the crashes happens in R_SortDrawSurfs:
-> render command list is too full
-> RE_EndFrame returns early because it can't allocate RC_SWAP_BUFFERS
-> R_ClearFrame in RE_EndFrame doesn't get called
-> the next frame starts with r_firstSceneDrawSurf etc. not being reset to 0
-> r_firstSceneDrawSurf becomes really close to the maximum draw surface limit
-> the draw surface list is iterated incorrectly (no wrapping handled)
-> we fetch a draw surface we shouldn't
-> its sort key gets decoded and we get an invalid sorted shader index
-> we fetch a NULL shader at that index location
-> we attempt to read shader->sort
-> we crash reading address 76
-> 76 bytes is exactly the offset of the sort member into the shader_t struct
