 # MultiPar
 
-### v1.3.3.1 is public
+### v1.3.3.2 is public
 
-  This is a testing version to improve speed of PAR2 calculation. 
-Because the new method isn't tested so much, there may be a bug, failure, or mistake. 
-Be careful to use this non-stable version. 
-When you don't want to test by yourself, you should not use this yet. 
+  This is a small fix version to improve performance of GPU acceleration. 
+It will become faster on AMD Radeon graphics boards. 
+It may be slightly faster on Nvidia GeForce graphics boards. 
+There is no difference in CPU calculation. 
+Because this isn't tested so much, there may be a bug, failure, or mistake. 
 If you see a problem, please report the incident. 
 I will try to solve as possible as I can.
 
-  CPU's L3 cache optimization depends on hardware environment. 
-It's difficult to guess the best setting for unknown type. 
-It seems to work well on Intel and AMD 's most CPUs. 
-Thanks Anime Tosho and MikeSW17 for long tests. 
-But, I'm not sure the perfomance of rare strange kind CPUs. 
-If you want to compare speed of different settings on your CPU, 
-you may try samples (TestBlock_2023-08-31.zip) in "MultiPar_sample" folder 
-on [OneDrive](https://1drv.ms/u/s!AtGhNMUyvbWOg0cF2UHcs709Icv4).
-
-  I improved GPU implementation very much. 
-Thanks [Slava46 and K2M74 for many tests](https://github.com/Yutaka-Sawada/MultiPar/issues/99). 
-While I almost gave up to increase speed, their effort encouraged me to try many ways. 
-Without their aid, I could not implement this GPU function. 
+  I changed 3 points in my OpenCL implementation. 
+It's possible to test them by `lc` option at command-line. 
+Thanks [cavalia88, Slava46, and Anime Tosho for many tests and wonderful idea](https://github.com/Yutaka-Sawada/MultiPar/issues/107). 
 OpenCL perfomance is varied in every graphics boards. 
 If you have a fast graphics board, enabling "GPU acceleration" would be faster. 
 If it's not so fast (or is slow) on your PC, just un-check the feature.
-
-  I saw a new feature of Inno Setup 6, which changes install mode. 
-It shows a dialog to ask which install mode. 
-Then, a user can install MultiPar in "Program Files" directory by selecting "Install for all users". 
-This method may be easier than starting installer by "Run as administrator". 
-I test the selection dialog at this version. 
-If there is no problem nor complaint from users, I use this style in later versions, too.
+1) Data transfur between PC's RAM and GPU's VRAM
+2) Calculation over GPU
+3) Calculate 2 blocks at once to reduce number of table lookup
 
 
-[ Changes from 1.3.3.0 to 1.3.3.1 ]  
-
-Installer update
-- It shows dialog to select "per user" or "per machine" installation.
+[ Changes from 1.3.3.1 to 1.3.3.2 ]  
 
 PAR2 client update
-- Change
-  - Max number of threads to read files on SSD was increased to 6.
-
 - Improvement
-  - GPU acceleration would become faster.
+  - GPU acceleration will work well on AMD graphics boards.
