خوب کسی جواب نمیده؟
این یه تسته که تو C++builer نوشتم و برای vs یکمی تفاوت داره در حد یکی دو خط مثلا برای "MHD" یه L به اولش اضافه کردم و یا تابع pow10 رو به شکل pow(10, ...)o نوشتم چون ارور میداد وگرنه بقیش مثل هم هست. سرعتشون تقریبا یکیه نمیشه گفت کدوم سریع تره. برنامه با Direct3D9 هست و یک قوری زرد با بکگراند آبی رو نمایش میده که تو مرکز مختصات داره دور خودش می چرخه. از سیستم نورافشانی دایرکت تریدی استفاده شده.
به هر حال وقتی برنامه اجرا شد پنجره تمام صفحه میشه بعد با alt + f4 برنامه رو ببندید، پنجره برنامه بسته میشه یم پنجره پیغام میاد که یک لیستی از فریم بر ثانیه که تو 25 فریم آخر ذخیره شده رو نمایش میده که اولین عدد از تقسیم کل فریم ها بر زمان کل نمایش بدست میاد و بقیشون (24 تای بعد) هم برای هر فریم جداگانه حساب شده. عدد اول تقریبا به شکل میانگین هست.

تو سیستم من تقریبا 1140 فریم بر ثانیه نمایش میدن هم با vs هم C++builder.
سرعت کامپایلر C++ builder یا visual C++ ؟؟؟
نوشته شده توسط (هیچکس)
) مقایسه با کد های مشابه درستر هست و من به شخصه بیشتر مایلم بدونم که اگه برنامه ای رو با C++builder کامپایل کنیم که بشه همون کد رو با کمی تغییر با VisualStudio کامپایل کرد (مثلا نخوایم خیلی از امکانات vcl استفاده کنیم) ، اونوقت سرعت اجرای برنامه تو کدوم بیشتر میشه؟ ضمن اینکه ما تو C++Builder هم می تونیم برنامه رو به شکل Win32 و بدون استفاده از VCL بنویسیم، همون طور که شما هم فرمودید اونوقت مایلیم که بدونیم سرعت تو کدوم بیشتره. مثل کدی که بنده نوشتم.
