I bought the new a2a 182 today. I was going to ask for a refund because even after a few minutes of flying when I used instant replay fsx became completely unstable visually and functionally. I had to close with task manager. The symptom was like running out of memory. I turned on dx10 and downloaded the dx10 fixer utility and the problem was completely eliminated. it was like mew life in fax on my computer plus all the great dx10 features. Thx!
