Intel HD 3000, The New Win 7 Drivers are faster but not multithreads safe.


Dear Intel Engineers/sw developers,

The new Intel HD 3000 drivers ( for Win 7 64bit are faster but not multithreads safe. Our non linear editing software, ivsEdits, crashes systematically in relation of the fault in ig4icd32.dll when two or more OpenGL sessions are executed at same time. Running the same code/application with both AMD and Nvidia GPUs there are not problems. We use OPENGL 2.1 extensions to resize video in Realtime (Picture In Picture) and if we apply the effect on the two Timelines layers we get crash on seeking only with INTEL GPUs. to learn more on ivsEdits please visit or
