Download a Shareware Version

To let you "try before buy" our products, evaluation versions are available for free download.
These Shareware versions of OptiVec and CMATH can be used for a full 90 days, before they cease functioning and remind you to get a registered copy.

The Shareware version of OptiVec comes with the following libraries:

1. 64-bit P8 debug library (down-compatible to Core2Duo and AMD64x2)
2. 64-bit P9M library, requiring 4th-generation Intel Core i (Haswell+) or AMD Excavator+, with auto-threading for multi-core processing and use of AVX, AVX2 and FMA3 for highest performance (which will be reached only for "heavy-weight" functions, however! If used in an app consisting mostly of light-weight functions like VF_addC, VF_round etc., some older processors react on the AVX2 instructions with down-clocking, so that the overall performance gets slower than with P8!)
3. 32-bit P4D debug library for full floating-point accuracy with the widest range of processor and operating system compatibility (down to 486DX / Pentium / Ahtlon and for all 32-bit Windows versions).
4. 32-bit P8M library with auto-threading for multi-core processing on processors ranging from the current ones down to Core2Duo or AMD64x2.

The Shareware version of CMath comes as the P8 and P4 (32-bit only) libraries.
