r. Streaming. MaxTempMemoryAllowed

"The amount of temporary memory in MB allowed for updating the textures. This should be big enough to avoid starving the texture streamer while

being small enough to prevent wasting (unused) memory."

Do not change it from the default value 50 too much higher, if the r. Streaming. PoolSize is too small, you will get blurry textures instead.
